Changes from v1:- 1. Replaced DRM_ERROR() with DRM_DEBUG_KMS() in malidp_format_mod_supported() to report unsupported modifiers. Changes from v2:- 1. Removed malidp_format_mod_supported() from the current patch. This has been added in "PATCH 7/12" 2. Dynamically generate the list of modifiers (to be supported for each plane) from 'malidp_format_modifiers' and features.
