Hi,
Caching the EDID via the firmware API makes the kernel able to reclaim
the memory in case it's needed. And eventually, the kernel will load it
again before suspending.
But for 128 bytes, even if we have many monitors it will not make any
difference.

Update XRGB-to-MONO conversion to support struct iosys_map
and convert all users. Although these are single-plane color formats,
the new interface supports multi-plane formats for consistency with
drm_fb_blit().

Merge drm_fb_memcpy() and drm_fb_memcpy() into drm_fb_memcpy() that
uses struct iosys_map for buffers. The new function also supports
multi-plane color formats. Convert all users of the original helpers.

Change format-conversion helpers to use struct iosys_map for source
and destination buffers. Update all users. Also prepare interface for
multi-plane color formats.
The format-conversion helpers mostly used to convert to I/O memory
or system memory. To actual memory type depended on the usecase.
Provide drm_fb_blit() that works with struct iosys_map. Update all
users of drm_fb_blit_toio(), which required a destination buffer in
I/O memory. The new function's interface works with multi-plane
color formats, although the implementation only supports a single
plane for now.
