pwm: dwc: allow suspend/resume for 16 channels
With 16 channel pwm support, we're registering two instances of pwm_chip
with 8 channels each. We need to update PM functions to use both instances
of pwm_chip during power state transitions.
Introduce struct dwc_pwm_drvdata and use it as driver_data, which will
maintain both instances of pwm_chip along with dwc_pwm_info and allow us
to use them inside suspend/resume handles.
Fixes: ebf2c89eb95e ("pwm: dwc: Add 16 channel support for Intel Elkhart Lake")
