[PATCH 1/2] pwm: atmel-hlcdc: Fix clock imbalance related to suspend support

[Uwe Kleine-König]

The suspend callback disables the periph clock when the PWM is enabled
and resume reenables this clock if the PWM was disabled before. Judging
from the code comment it's suspend that is wrong here. Fix accordingly.
