The value of mt8195_mutex_sof will be set into this register,
#define MT8195_DISP_MUTEX0_SOF 0x2c
which is providing the source module selection of SOF(Start of Frame)
and EOF(End of Frame) in current stream(MUTEX).
MUTEX will send the EOF trigger signal to all sourcesub-module whose
EOF is selected in this register.
So I think we should or EOF to make sure sub-module cloud get both SOF
and EOF trigger signal for status checking, error handling or
debugging.

MUTEX_SOF_DP_INTF1 won't use in vdosys0, so it will be added at the
patch [1] in vdosys1 series.
