[PATCH v3 5/6] drm/msm/dp: Enable ASSR for supported DP sinks

[Stephen Boyd]

Quoting Sankeerth Billakanti (2021-10-27 18:54:47)
> The eDP sink on sc7280 supports ASSR and dp driver will
> enable ASSR in the source hardware. The driver needs to
> enable the ASSR field in the DPCD configuration register
> to avoid screen corruption. This change will enable ASSR
> if supported in the sink device.
