This patch modifies the hvm_function_table.virtual_intr_delivery_enabled()
to become a bool variable as both VMX and SVM simply return static value.
Also, this patch hooks up virtual_intr_delivery_enabled and
deliver_posted_intr functions when AVIC is enabled.

Introduce AVIC base initialization code. This includes:
* Setting up per-VM data structures.
* Setting up per-vCPU data structure.
* Initializing AVIC-related VMCB bit fields.

Enabling AVIC implicitly disables the V_IRQ, V_INTR_PRIO, V_IGN_TPR,
and V_INTR_VECTOR fields in the VMCB Control Word. Therefore, this patch
introduces new interrupt injection code via AVIC backing page.

OVERVIEW
This patchset is the first of a two-part patch series to introduce
the AMD Advanced Virtual Interrupt Controller (AVIC) support.
The AVIC hardware virtualizes local APIC registers of each vCPU via
the virtual APIC (vAPIC) backing page. This allows the guest to access
certain APIC
