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

pm_vuart stops listening and relays the message right away if it
encounters EAGAIN during read(). This causes the messages relayed to be
fragmented.
Only relay the message when it encounters a null character or a newline

set the attributes during pm-vuart initialization
to avoid the pm-vuart in an indefinite state.
Currently we have implemented S5 triggered by SOS,
these patch series both support S5 triggered by SOS and RTVM.
the fully steps for S5 triggered by SOS:
1) S5-Trigger: it initiates the platform shutdown actions;
it calls “acrnctl stop vmX” to do that,
and check the VM's status, power-off SOS itself.
2) acrnctl will send “stop” to “acrn-dm”
3) acrn-dm will send “shutdown” command to VMx by v-UART.
4) when life-cycle manager in VMx receives the “shutdown” command,
it will give an “acked” to acrn-dm, and then poweroff itself.
the fully steps for S5 triggered by RTVM:
1) S5-Trigger in RTVM: it initiates the platform shutdown actions;
it’ll send shutdown command for platform shutdown to
life-cycle manager
2) when life-cycle manager in RTVM receive the message,
it will send “shutdown” command to acrn-dm in SOS by v-UART.
3) when acrn-dm receives the “shutdown” command from RTVM,
it will give an “acked” to RTVM, RTVM’s life-cycle manager can
power off itself
4) acrn-dm will send “shutdown” command to its own life-cycle manager
by socket.
5) when life-cycle manager in SOS receives the “shutdown” command,
it can call “s5_trigger” script to shutdown platform.
