At least freeze, restore and thaw need to be set in order for the driver
to support system hibernation. The existing suspend/resume functions can
be reused since those functions don't touch the device's power state or
wakeup capability. Use the helper macros SET_SYSTEM_SLEEP_PM_OPS and
SET_NOIRQ_SYSTEM_SLEEP_PM_OPS for symmetry with similar drivers.

Looks sensible, although you should also test the other sleep methods,
e.g. suspend to idle.

Yes, s2idle still works. Standby / Power-On Suspend and s2ram we don't have support for so I can't test it. Thanks for the review!
