pwm: rcar: Prepare removing pwm_chip from driver data
This prepares the driver for further changes that will drop struct
pwm_chip chip from struct rcar_pwm_chip. Use the pwm_chip as driver
data instead of the rcar_pwm_chip to get access to the pwm_chip in
the .remove() callbacks without using rcar_pwm->chip.
