hv: introduce SRIOV interception

Browse Source 
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.
