pwm: stm32: Simplify code to determine the pwmchip's parent device

There is already a pointer to the pwmchip, make use of it directly
instead of using the struct stm32_pwm *priv just obtained from it. This
also has the advantage of not using struct stm32_pwm::chip any more
which will be dropped soon.
