Since vmexit handling in ACRN partition mode is not complex (since no SOS and
all devices passthru), interrupts can stay disabled in root mode during
vmexit handling.

ACRN in partition mode does not have vector and APIC ID remapping for
device interrupts. Only MSIs are supported. No IOAPIC and legacy interrupts
for the VMs in ACRN partition mode.

'hv_main()' wraps several logic which has no dependencies
each other(enable VMX, prepare to create service os VM..),
in this case, split this function to make code logic clear.
remove 'is_vm0_bsp()' & 'hv_main()'

MISRA C requires that all unsigned constants should have
the suffix 'U/UL'(e.g. 0xffU), but the assembler may not
accept such C-style constants.
To work this around, HOST_GDT_RING0_CODE_SEL and
HOST_GDT_RING0_DATA_SEL must be explicitly spells
out in assembly with a comment tracking the original
expression from which the magic number is calculated.
V1-->V2:
Update commit information about HOST_GDT_RING0_CODE_SEL
and HOST_GDT_RING0_DATA_SEL.
V2-->V3:
Update comment for HOST_GDT_RING0_CODE_SEL in assembly
code.
