2021-03-23	drm/amd/display: add a func to disable accelerated mode	Yao Wang1	1	-1/+1
	[Why] When driver disabled, we driver force the YCbCr420 to RGB, which means some register will be changed, such as RDPCS_PHY_DP_MPLLB_TX_CLK_DIV changed from 1 to 0 When driver re-enabled, OS will Set Mode YCbCr420 again, which means the register RDPCS_PHY_DP_MPLLB_TX_CLK_DIV should to be 1 again, but dmub fw can’t update the register to 1 due to the mpll is not off [How] Adds an interface to disable accelerated mode bit, which allows DM to decide to call during driver disable/unload scenarios.
