7d8803f5ea hv:enable APICv features based on CPU capability
this patch is to detect and enable only APICv features which
are actually supported by the processor, instead fo tuning on
all features by default.

a87757d602 uefi: remove old interrupt injection method
we added uefi stub for hv, and want vm0 continue running under uefi env to
boot other uefi payload (osloader or bzImage).

during this, the uefi timer irq need be handled elegantly.

there are 3 types for uefi timer:
1. 8254 based on IRQ0 of PIC
2. HPET based on IOAPIC
3. HPET based on MSI

currently, we only support type 3 (HPET+MSI). But we are following a
in-correct flow to handle this timer interrupt:
- we set VMX_ENTRY_INT_INFO_FIELD directly if a timer interrupt happened
  before vcpu launching, this will make its vlapic mess up, which finally
  cause hpet timer stop.

this patch remove this in-correct approach, the new approach patch will
be followed by next patch.
