Improve `acrn-dm` power management-related parameters #5990

Open gvancuts opened 3 years ago

We should combine --pm_notify_channel and --pm_by_vuart into a single parameter. E.g.:

--pm_notify_channel vuart,/dev/ttyS1 means it's a vUART implemented by the hypervisor
--pm_notify_channel vuart,/run/acrn/pm_vmX means it's a vUART implemented by ACRN Device Model ('acrn-dm')
--pm_notify_channel [ioc|power_button] behave as before

We should also make it clear via documentation that:

Using the hypervisor-land vUART is required for an RTVM (to not break its realtime characteristics).
Hypervisor-land vUARTs should be defined in the scenario XML file, else it won't exist (and a meaningful error should be thrown by acrn-dm when attempting to use it)

These parameters were already removed, @weichenli-intel , please help to check and remove in referenced doc.
