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.

- Converted MACROS to functions
- Defined pci_bar_type enum
- Defined pci_bdf as union instead of uint16_t to eliminate macros
- Use L or UL postfix after unsigned integers

VMs in partition mode uses a kernel patch to switch to physical mode xAPIC.
The kernel patch together with this patch makes sure device MSIs use
physical mode as DM and physical APIC IDs in Destination field.

1) Changed VM memory size from 2 GB to 512 MB
Some platforms might not have a total of 4 GB above 4 GB in host e820
With this change, we need a total of only 1 GB above 4 GB in host e820
2) Update e820 entries for the above change
3) type fix for VM1_CPUS and VM2_CPUS

partition mode.
2) Moves vm_description entries from bsp/sbl/ to partition/
3) Removes unused API get_vm_desc_base

V4:
- Renamed members for struct pcibar and changed code accordingly
V3:
- Do not use ASSERT
- Use EPT_XX defines when claling ept_mr_add
- Report 64-bit MMIO physical bar to UOS as 32-bit virtual bar
(assume bar size is always less than 4GB), which removed quite some of
64-bit bar handling code
