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