hv: Enumerate IOAPIC info from MADT

Browse Source 
IOAPIC info, specifically ID, is needed to map the IOAPIC to
corresponding DMAR. DMAR table in ACPI has a field that has IOAPIC
ID, that matches the info provided in MADT. Both (IOAPIC info from
MADT and from DMAR) is needed for remapping IOAPIC interrupts.
