drm/rockchip: vop: Set mcu mode before setting output mode and dither

Browse Source 
When drive vop into mcu mode with mcu_hold enabled,
the following setting of output mode and dither will
not take effect until mcu_hold released.

So we can send mcu cmd at the default output P888 mode,
this give us a changce to avoid the cmd data to be changed
by dither module.
