drm: Define DRM_FORMAT_MAX_PLANES
DRM uses a magic number of 4 for the maximum number of planes per color
format. Declare this constant via DRM_FORMAT_MAX_PLANES and update the
related code. Some code depends on the length of arrays that are now
declared with DRM_FORMAT_MAX_PLANES. Convert it from '4' to ARRAY_SIZE.
v2:
* mention usage of ARRAY_SIZE() in the commit message (Maxime)
* also fix error handling in drm_gem_fb_init_with_funcs()
(kernel test robot)
* include <drm/drm_fourcc.h> for DRM_FORMAT_MAX_PLANES
