VMWARE_HYPERCALL alternative will not work as intended without VMware guest code
initialization.
[ bp: note that this doesn't reproduce with newer gccs so it must be
something gcc-9-specific. ]

Instead of using vmwgfx specific framebuffer implementation use the drm
fb helpers. There's no change in functionality, the only difference
is a reduction in the amount of code inside the vmwgfx module.
drm fb helpers do not deal correctly with changes in crtc preferred mode
at runtime, but the old fb code wasn't dealing with it either.
Same situation applies to high-res fb consoles - the old code was
limited to 1176x885 because it was checking for legacy/deprecated
memory limites, the drm fb helpers are limited to the initial resolution
set on fb due to first problem (drm fb helpers being unable to handle
hotplug crtc preferred mode changes).
This also removes the kernel config for disabling fb support which hasn't
been used or supported in a very long time.

This is initial change adding support for DRIVER_GEM to vmwgfx. vmwgfx
was written before GEM and has always used TTM. Over the years the
TTM buffers started inherting from GEM objects but vmwgfx never
implemented GEM making it quite awkward. We were directly setting
variables in GEM objects to not make DRM crash.
This change brings vmwgfx inline with other DRM drivers and allows us
to use a lot of DRM helpers which have depended on drivers with GEM
support.
Due to historical reasons vmwgfx splits the idea of a buffer and surface
which makes it a littly tricky since either one can be used in most
of our ioctl's which take user space handles. For now our BO's are
GEM objects and our surfaces are opaque objects which are backed by
GEM objects. In the future I'd like to combine those into a single
BO but we don't want to break any of our existing ioctl's so it will
take time to do it in a non-destructive way.

VMware mks-guest-stats mechanism allows the collection of performance stats from
guest userland GL contexts, as well as from vmwgfx kernelspace, via a set of sw-
defined performance counters. The userspace performance counters are (de)registerd
with vmware-vmx-stats hypervisor via new iocts. The vmwgfx kernelspace counters
are controlled at build-time via a new config DRM_VMWGFX_MKSSTATS.
* Add vmw_mksstat_{add|remove|reset}_ioctl controlling the tracking of
mks-guest-stats in guest winsys contexts
* Add DRM_VMWGFX_MKSSTATS config to drivers/gpu/drm/vmwgfx/Kconfig controlling
the instrumentation of vmwgfx for kernelspace mks-guest-stats counters
* Instrument vmwgfx vmw_execbuf_ioctl to collect mks-guest-stats according to
DRM_VMWGFX_MKSSTATS

This change fixes all of the arm64 issues we've had in the driver.
ARM support is provided in svga version 3, for which support we've added
in previous changes. svga version 3 currently lacks many of the
advanced features (in particular 3D support is lacking) but
that will change in time.

Respect DRM's kconfig setting for fbdev console emulation. If enabled,
it will select all required config options. So remove them from vmwgfx's
Kconfig file.

This infrastructure will, for coherent resources, make sure that
from the user-space point of view, data written by the CPU is immediately
automatically available to the GPU at resource validation time.

vmwgfx doesn't actually build without that.
It would be great if vmwgfx could switch over to the fbdev emulation
helpers, since those will take care of all this already. I guess one
reason to not do that was lack of defio support in the helpers, but
that's fixed now. If there's any other hold-up, we should figure out
what it is and whether it makes sense to address it.

The drm core shouldn't depend upon any helpers, and we make sure this
doesn't accidentally happen by moving them into the helper-only
drm_kms_helper.ko module.
v2: Don't break the build for vmwgfx, spotted by Matt.
v3: Unbreak the depency loop around CONFIG_FB (not actually a loop
since it involves select). Reported by Chris.

vmwfgx uses framebuffer interfaces, so it should depend on FB.
Otherwise it has these build errors (e.g., when CONFIG_FB=m):

This commit adds the vmwgfx driver for the VWware Virtual GPU aka SVGA.
The driver is under staging the same as Nouveau and Radeon KMS. Hopefully
the 2D ioctls are bug free and don't need changing, so that part of the
API should be stable. But there there is a pretty big chance that the 3D API
will change in the future.
