Implement saving and restoring context of the PWM controller when the
application goes to SYS_PM_DEEP_SLEEP. No action is taken for other
states at the moment.
This functionality is implemented in the shim driver first to enable
the feature, but will later be moved into QMSI.

The suspend and resume hooks in the pwm_driver_api struct are relics
from before the current power management infrastructure was in place.
The correct way to implement this now is through the device_pm_ops
struct, by way of the DEFINE_DEVICE_PM_OPS and DEVICE_AND_API_INIT_PM
macros, which make the hooks available through a generic mechanism for
all devices, rather than using per-type APIs.
Since the existing pwm_suspend() and pwm_resume() functions don't check
if the driver_api hooks are NULL, there's now a place holder function
to prevent breaking functionality until the hooks are removed.

CONFIG_PWM=y
CONFIG_PWM_QMSI=y
Optionally this can be set:
