msm: mdss: dp: fix switching between non-standard resolutions
EDID parser assigns temporary Video Identification Codes (VIC) for
all non-standard resolutions when parsing a sink's EDID. These
VICs can be reused for a subsequent connection for different
resolutions. In the current implementation of the Display Port (DP)
driver, a resolution change is detected whenever a new VIC is used.
However, when switching between two non-standard resolutions spanning
connections to two different sinks, it is possible to have the same
VIC assigned for the two resolutions. This can result in abnormal
behavior. Fix this by resetting the video identification code and panel
information to reset value every time we get an HPD for disconnect.
