drm/msm/dp: split MMSS_DP_DSC_DTO register write to a separate function

Browse Source 
It's the dp_panel's duty to clear the MMSS_DP_DSC_DTO register. Once DP
driver gets DSC support, it will handle that register in other places
too. Split a call to write 0x0 to that register to a separate function.
