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