pwm: dwc: Prepare removing pwm_chip from driver data
This prepares the driver for further changes that will drop struct
pwm_chip chip from struct dwc_pwm. Use the pwm_chip as driver
data and return value of dwc_pwm_alloc() instead of the dwc_pwm to get
access to the pwm_chip in dwc_pwm_probe() and dwc_pwm_suspend() without
using dwc->chip.
Thanks to Raag Jadav for providing a hunk of this patch that Uwe missed
during creation of this patch.
