pwm: sun4i: Prepare removing pwm_chip from driver data
This prepares the driver for further changes that will drop struct
pwm_chip chip from struct sun4i_pwm_chip. Use the pwm_chip as driver
data instead of the sun4i_pwm_chip to get access to the pwm_chip in
sun4i_pwm_remove() without using sun4ichip->chip.
