tty: serial: samsung: Set missing PM ops for hibernation support 



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.
