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.
