msm: mdss: sink mode needs to be read from EDID

DVI/HDMI mode of sink could be read from EDID. Now, we set
the mode according to the video format. For a HDMI device,
if we choose VIC mode larger than 127, it would be set as
DVI mode. It would be confused that a HDMI device is treated
as a DVI device, and would lead some issue for display.
