drm: add docs about the IN_FORMATS plane property
This is a standard property attached to planes in drm_universal_plane_init when drm_mode_config.allow_fb_modifiers is true.

+ * Blob property which contains the set of buffer format and modifier
+ * pairs supported by this plane. The blob is a drm_format_modifier_blob

* exposed and assumed to be black).
