hwmon: (it87) Fix pwm4 detection for IT8620 and IT8628
pwm4 is enabled if bit 2 of GPIO control register 4 is disabled,
not when it is enabled. Since the check is for the skip condition,
it is reversed. This applies to both IT8620 and IT8628.
Fixes: 36c4d98a7883d ("hwmon: (it87) Add support for all pwm channels ...")
