Subject: drm/vc4: hdmi: Set VC4_HDMI_MAI_CONFIG_FORMAT_REVERSE
Git-commit: 9a8fd277a82c2ac7d6af7422088de6c469419cc4
Patch-mainline: v5.15-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
Without this bit set, HDMI_MAI_FORMAT doesn't pick up
the format and samplerate from DVP_CFG_MAI0_FMT and you
can't get HDMI_HDMI_13_AUDIO_STATUS_1 to indicate HBR mode
