It is possible that controller may become suspended between processing a
phyup interrupt and the event being processed by libsas. As such, we can't
ensure the controller is active when processing the phyup event - this may
cause the phyup event to be lost or other issues.  To avoid any possible
issues, add pm_runtime_get_noresume() in phyup interrupt handler and
pm_runtime_put_sync() in the work handler exit to ensure that we stay
always active. Since we only want to call pm_runtime_get_noresume() for v3
hw, signal this will a new event, HISI_PHYE_PHY_UP_PM.
