pwm: omap-dmtimer: Prepare removing pwm_chip from driver data
This prepares the driver for further changes that will drop struct
pwm_chip chip from struct pwm_omap_dmtimer_chip. Use the pwm_chip as
driver data instead of the pwm_omap_dmtimer_chip to get access to the
pwm_chip in pwm_omap_dmtimer_remove() without using omap->chip.
