pwm: stm32-lp: Prepare removing pwm_chip from driver data
This prepares the driver for further changes that will drop struct
pwm_chip chip from struct stm32_pwm_lp. Use the pwm_chip as driver
data instead of the stm32_pwm_lp to get access to the pwm_chip in
stm32_pwm_lp_suspend() without using priv->chip.
