Subject: drm/vc4: hdmi: Add MISC_CONTROL register for vc4
Git-commit: f3f27511316bd14ebf0a3c0f76aafced59e541df
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
The MISC_CONTROL register allows configuration of pixel repetition
for pixel doubling in the HDMI block instead of PixelValve.
It was already defined for vc5, so add it for vc4.
