pwm: Clear chip_data in pwm_put()
commit e926b12c611c2095c7976e2ed31753ad6eb5ff1a upstream.
After a PWM is disposed by its user the per chip data becomes invalid.
Clear the data in common code instead of the device drivers to get
consistent behaviour. Before this patch only three of nine drivers
cleaned up here.
