Display driver read DPCD register 0x202, 0x203 and 0x204 to identify
eDP sink status.If PSR exit is ongoing at eDP sink, and eDP source
read these registers at the same time. Panel will report EQ & symbol
lock not done. It will cause panel display flicking.

is ongoing before EQ done. Panel will report EQ & symbol lock
not done. Both of them are under progressing at the same time
