This was based on a patch originally by Kristian. It has been modified pretty heavily to use the new callbacks from the previous patch.
v2: - Add LINEAR and Yf modifiers to list (Ville) - Combine i8xx and i965 into one list of formats (Ville) - Allow 1010102 formats for Y/Yf tiled (Ville)
v3: - Handle cursor formats (Ville) - Put handling for LINEAR in the mod_support functions (Ville)
v4: - List each modifier explicitly in supported modifiers (Ville) - Handle the CURSOR plane (Ville)
v5: - Split out cursor and sprite handling (Ville)
v6: - Actually use the sprite funcs (Emil) - Use unreachable (Emil)
v7: - Only allow Intel modifiers and LINEAR (Ben)
v8 - Fix spite assert introduced in v6 (Daniel)
v9 - Change vendor check logic to avoid magic 56 (Emil) - Reorder skl_mod_support (Ville) - make intel_plane_funcs static, could be done as of v5 (Ville) - rename local variable intel_format_modifiers to modifiers (Ville) - actually use sprite modifiers - split out modifier/formats by platform (Ville)
