drm/vc4: Add support for SAND modifier.
This is the format generated by VC4's H.264 engine, and preferred by
the ISP as well. By displaying SAND buffers directly, we can avoid
needing to use the ISP to rewrite the SAND H.264 output to linear
before display.
This is a joint effort by Dave Stevenson (who wrote the initial patch
and DRM demo) and Eric Anholt (drm_fourcc.h generalization, safety
checks, RGBA support).
v2: Make the parameter macro give all of the middle 48 bits (suggested
by Daniels). Fix fourcc_mod_broadcom_mod()'s bits/shift being
swapped. Mark NV12/21 as supported, not YUV420.
