Subject: drm/vc4: hdmi: Move XBAR setup to csc_setup
Git-commit: 0cbb53b283d325fb90c3ab39c300c085bb7ac2f8
Patch-mainline: v5.18-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
On the BCM2711, the HDMI_VEC_INTERFACE_XBAR register configuration
depends on whether we're using an RGB or YUV output. Let's move that
configuration to the CSC setup.
