drm/core: Calculate bpp in afbc helper

Browse Source 
Some drivers (komeda, malidp) don't set anything in cpp. If that is the
case the right value can be inferred from the format. Then the "bpp" member
can be eliminated from struct drm_afbc_framebuffer.

Encode cpp properly in malidp
-----------------------------
cpp (chars per pixel) is not encoded properly in malidp, zero is
used instead. afbc implementation needs bpp or cpp, but if it is
zero it needs to be provided elsewhere, and so the bpp field exists
in struct drm_afbc_framebuffer.
Properly encode cpp in malidp and remove the bpp field in struct
drm_afbc_framebuffer.
