A user can use "--pm_notify_channel uart,allow_trigger_s5" to indicate
the User VM is allowed to trigger system S5.
"--pm_notify_channel uart" means a vuart channel will be created in the
User VM to allow communication with the VM's life_mngr. The Service VM
can then initiate S5 in the guest via its dm's monitor interface. The
additional option, "allow_trigger_s5", will create a socket connection
with the Service VM's life_mngr, allowing this VM to initiate system S5.
v1 -> v2:
- rename pm_notify_channel type to PWR_EVENT_NOTIFY_UART_TRIG_PLAT_S5
