doc: change term of vm0 to sos_vm

Browse Source 
Using term of VM0 would mislead to a VM with VM id 0 easily, whereas
VM id 0 could be used for any PRE_LAUNCHED_VM. So replace VM0 with
SOS_VM.

ACPI Emulation
--------------
An alternative ACPI resource abstraction option is for the SOS (VM0) to
own all devices and emulate a set of virtual devices for the UOS (VM1).
An alternative ACPI resource abstraction option is for the SOS (SOS_VM) to
own all devices and emulate a set of virtual devices for the UOS (NORMAL_VM).
This is the most popular ACPI resource model for virtualization,
as shown in the picture below. ACRN currently
uses device emulation plus some device passthrough for UOS.
