mb/google/corsola: Fix MIPI panel power on/off sequence
Based on the power sequence of the panel [1] and PMIC datasheet [2],
the power on T2 sequence VSP to VSN should be large than 1ms, but it's
-159us now, and the power off T2 sequence VSP to VSN should be large
than 0ms, but it's less than 0 now. Let's modify the power sequence
to meet the datasheet requirement.
