Sainath Grandhi 48ae379b4b hv: LAPIC pass-thru support for partition mode of ACRN
ACRN, in partition mode, supports LAPIC pass-thru to guests. Guest needs
to use x2APIC mode of LAPIC for pass-thru to be enabled.

ACRN also needs the user to configure lapic_pt to true in vm_desc
for the VM.

Interrupt Command Register (ICR) is the only APIC register that is
intercepted. Reference code in partition/vm_description.c enables
LAPIC pass-thru for vm2.
