drm/vc4: hvs: Don't write gamma luts on 2711

Browse source

[ Upstream commit 52efe364d1 ]

The gamma block has changed in 2711, therefore writing the lut
in vc4_hvs_lut_load is incorrect.

Whilst the gamma property isn't created for 2711, it is called
from vc4_hvs_init_channel, so abort if attempted.
