ENGR00223348 EPDC: Unable to enable DISPLAY regulator
In the maxim 17135 driver, the power good is confirmed by the
power good GPIO polarity change when comparing the status at
the beginning of driver probe and display regulator enabled.
However, it is not reliable since the initial value of the GPIO
is not constant. Normally, it is 1 but it can be 0 after system reset
unexpectedly. Now, it is changed to POK bit checking in FAULT register.
