Use the regular fbdev helpers for framebuffer I/O instead of DRM's
helpers. Omapdrm does not use damage handling, so DRM's fbdev helpers
are mere wrappers around the fbdev code.
By using fbdev helpers directly within each DRM fbdev emulation,
we can eventually remove DRM's wrapper functions entirely.

* use initializer macros for struct fb_ops
v2:
* use FB_SYS_HELPERS option

Move code from ad-hoc fbdev callbacks into DRM client functions
and remove the old callbacks. The functions instruct the client
to poll for changed output or restore the display. The DRM core
calls both, the old callbacks and the new client helpers, from
the same places. The new functions perform the same operation as
before, so there's no change in functionality.
Replace all code that initializes or releases fbdev emulation
throughout the driver. Instead initialize the fbdev client by a
single call to omapdrm_fbdev_setup() after omapdrm has registered
its DRM device. As in most drivers, omapdrm's fbdev emulation now
acts like a regular DRM client.
The fbdev client setup consists of the initial preparation and the
hot-plugging of the display. The latter creates the fbdev device
and sets up the fbdev framebuffer. The setup performs display
hot-plugging once. If no display can be detected, DRM probe helpers
re-run the detection on each hotplug event.
A call to drm_dev_unregister() releases the client automatically.
No further action is required within omapdrm. If the fbdev
framebuffer has been fully set up, struct fb_ops.fb_destroy
implements the release. For partially initialized emulation, the
fbdev client reverts the initial setup.

* init drm_client in this patch (Tomi)

Move drm_fb_helper_unprepare() from drm_fb_helper_fini() into the
calling fbdev implementation. Avoids a possible stale mutex with
generic fbdev code.
As indicated by its name, drm_fb_helper_prepare() prepares struct
drm_fb_helper before setting up the fbdev support with a call to
drm_fb_helper_init(). In legacy fbdev emulation, this happens next
to each other. If successful, drm_fb_helper_fini() later tear down
the fbdev device and also unprepare via drm_fb_helper_unprepare().
Generic fbdev emulation prepares struct drm_fb_helper immediately
after allocating the instance. It only calls drm_fb_helper_init()
as part of processing a hotplug event. If the hotplug-handling fails,
it runs drm_fb_helper_fini(). This unprepares the fb-helper instance
and the next hotplug event runs on stale data.
Solve this by moving drm_fb_helper_unprepare() from drm_fb_helper_fini()
into the fbdev implementations. Call it right before freeing the
fb-helper instance.

The fb_base in struct drm_mode_config has been unused for a long time.
Some drivers set it and some don't leading to a very confusing state
where the variable can't be relied upon, because there's no indication
as to which driver sets it and which doesn't.
The only usage of fb_base is internal to two drivers so instead of trying
to force it into all the drivers to get it into a coherent state
completely remove it.

This is a no-op on atomic drivers because with atomic it's simply too
complicated to get all the locking and workers and nonblocking
synchronization correct, from essentially an NMI context. Well, too

omap_fbdev_init() and omap_fbdev_free() use priv->fbdev directly.
However, omap_fbdev_init() returns the fbdev, and omap_drv.c also
assigns the return value to priv->fbdev. This is slightly confusing.
Clean this up by removing the omap_fbdev_init() return value, as we
don't care whether fbdev init succeeded or not. Also change omap_drv.c
to call omap_fbdev_free() always, and omap_fbdev_free() does the check
if fbdev was initialized.
While at it, rename omap_fbdev_free() to omap_fbdev_fini() to better
match the "init" counterpart.

Instead of receiving the num_crts as a parameter, we can read it

invoke this helper and I believe all of them initialize the mode_config

I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates. The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.

It's a legacy helper function which won't do good with atomic helpers.

At the moment we calculate the buffer's pitch with:
pitch = width * DIV_ROUND_UP(bpp, 8)
For CLUT modes with bpp of 1/2/4/8 this gives wrong result, and the
correct pitch is:
pitch = DIV_ROUND_UP(width * bpp, 8)
In practice this doesn't change anything, as we don't support CLUT
modes, but it's better to have the pitch calculation correct.

The previous commit removed aligning the pitch to SGX's pitch
requirement from align_pitch(). What's left is effectively a function
that returns width * bytespp.
To clean up the driver, we can remove the function and have the
calculation inline in the two places which call align_pitch().

For drm_gem_object_unreference callers are required to hold
dev->struct_mutex, which these paths don't. Enforcing this requirement
has become a bit more strict with

Don't compile the fbdev emulation code when fbdev emulation support is
disabled.

omap_fbdev always creates a framebuffer with ARGB8888 pixel format. On
OMAP3 we have VIDEO1 overlay that does not support ARGB8888, and on
OMAP2 none of the overlays support ARGB888.
This patch changes the omap_fbdev's fb to XRGB8888, which is supported
by all platforms.

Use the newly created wrapper drm_fb_helper functions instead of calling
core fbdev functions directly. They also simplify the fb_info creation.
v3:
- Update error handling for new drm_fb_helper funcs. Check using IS_ERR()
instead of checking for NULL.

v2:
- No changes
