pwm: samsung: 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 samsung_pwm_chip *our_chip just obtained
from it. This also has the advantage of not using struct
samsung_pwm_chip::chip any more which will be dropped soon.
