EPT/VT-d: bug fix for EPT/VT-d table sharing
This patch makes following changes: 1) Moves EPT/VT-d sharing
initialization back to when it is actually needed to make sure
vmx_ept_vpid_cap has been initialized. 2) added page order parameter
to iommu_pte_flush() to tell VT-d what size of page to flush. 3)
added hap_2mb flag to ease performance studies between base 4KB EPT
size and when 2MB and 1GB page size support are enabled.
