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

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