Currently even the SoC's OVL does not declare the support of AFBC, AFBC
is still announced to the userspace within the IN_FORMATS blob, which
breaks modern Wayland compositors like KWin Wayland and others.
Gate passing modifiers to drm_universal_plane_init() behind querying the
driver of the hardware block for AFBC support.
