[v6,098/164] pwm: samsung: Make use of pwmchip_parent() accessor

Series [v6,001/164] pwm: Provide an inline function to get the parent device of a given chip | expand

struct pwm_chip::dev is about to change. To not have to touch this
driver in the same commit as struct pwm_chip::dev, use the accessor
function provided for exactly this purpose.
