All SRIOV VF physical devices don't have bars in configuration space,
they are from the VF associated PF's VF_BAR registers of SRIOV capability.
Adding a vbars data structure in pci_cap_sriov data structure to store
SRIOV VF_BAR information, so that each VF bars can be initialized directly
through the vbars instead multiple accessing of the PF VF_BAR registers.

VF_ENABLE is one field of SRIOV capability that is used to create
or remove VF physical devices. If VF_ENABLE is set, hv can detect
if the VF physical devices are ready after waiting 100 ms.
v2: Add sanity check for writing NumVFs register, add precondition
and application constraints when VF_ENABLE is set and refine
code style.
