[PATCH 2/5] video: simplefb-fixup: use shared SIMPLEFB_FORMATS table

[Ahmad Fatoum <a.fatoum@barebox.org>]

The driver maintained a private 2-entry format table covering only r5g6b5
and a8r8g8b8. The shared SIMPLEFB_FORMATS macro in
<linux/platform_data/simplefb.h> covers all formats defined by the DT
binding.

Replace the private struct simplefb_mode and simplefb_modes[] with
the shared struct simplefb_format and SIMPLEFB_FORMATS and while at it,
drop <common.h> in favour of the specific headers actually needed.
