This replaces drm_fb_swab16() with drm_fb_swab() supporting 16 and 32-bit.
Also make pixel line caching optional.

drm_format_info_plane_cpp() basically just returns the cpp array content
found in the drm_format_info structure.
Since it's pretty trivial, let's remove the function and have the users use
the array directly

So far, the drm_format_plane_cpp function was operating on the format's
fourcc and was doing a lookup to retrieve the drm_format_info structure and
return the cpp.
However, this is inefficient since in most cases, we will have the
drm_format_info pointer already available so we shouldn't have to perform a
new lookup. Some drm_fourcc functions also already operate on the
drm_format_info pointer for that reason, so the API is quite inconsistent
there.
Let's follow the latter pattern and remove the extra lookup while being a
bit more consistent. In order to be extra consistent, also rename that
function to drm_format_info_plane_cpp and to a static function in the
header to match the current policy.

Also drop the dstclip parameter sphinx has warned about (leftover from
an earlier patch version).

Oops, the __iomem annotation was added to the header file only.
Add it to the implementation (and documentation) too.
Fixes: 5c5373b51bec ("drm: switch drm_fb_xrgb8888_to_rgb888_dstclip to accept __iomem dst")

Not all archs have the __io_virt() macro, so cirrus can't simply convert
pointers that way. The drm format helpers have to use memcpy_toio()
instead.
This patch makes drm_fb_xrgb8888_to_rgb888_dstclip() accept a __iomem
dst pointer and use memcpy_toio() instead of memcpy(). The helper
function (drm_fb_xrgb8888_to_rgb888_line) has been changed to process a
single scanline.

This patch makes drm_fb_memcpy_dstclip() accept a __iomem dst pointer
and use memcpy_toio() instead of memcpy(). With that separating out the
memcpy loop into the drm_fb_memcpy_lines() helper isn't useful any more,
so move the code back into the calling functins.

Simliar to drm_fb_xrgb8888_to_rgb565_dstclip() but converts to rgb888
instead of rgb565.

It is a drm_fb_xrgb8888_to_rgb565() variant which checks the clip
rectangle for the destination too.
Common code between drm_fb_xrgb8888_to_rgb565() and
drm_fb_xrgb8888_to_rgb565_dstclip() was factored out into the
drm_fb_xrgb8888_to_rgb565_lines() helper function.
