gpio: pca953x: propagate regulator_enable() error from resume

pca953x_resume() returns 0 when regulator_enable() fails, dropping
the real error code and masking the failure as a successful resume.
The caller then proceeds as if the chip is powered, while the
regulator is in fact disabled.

Return ret so PM core sees the actual failure.
