hwmon: (it87) Fix pwm4 detection for IT8620 and IT8628

Browse Source 
commit d66777caa57ffade6061782f3a4d4056f0b0c1ac upstream.

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.
