fm10k: add VF support
fm10k: add VF support

fm10k pmd driver will support both PF and VF device with single
copy of code. The reason is NIC maps registers with same
function in PF and VF to same PCI I/O address. Then, PF/VF drivers
use same address to access registers belonging to it, HW will
translate the request to correct units.

For some functionalities that are unique to PF, driver will check
current driver type and behave correctly.
