[PATCH v3 015/108] pwm: lpc18xx-sct: Make use of parent device pointer in driver data

[Uwe Kleine-König]

struct pwm_chip::dev is about to change. To not have to touch this
driver in the same commit as struct pwm_chip::dev, make use of the
already existing pointer to the parent device in driver data. However
rename the pointer to "parent" for consistency with other drivers.
