Fix number of the enabled VFs in VNIC

Fix number of the enabled VFs in VNIC

nic->num_vf_en is set based on the number of the enabled LMACs.
This number should not be overwritten later by any routine.
Instead it should fail PCI_IOV_ADD_VF() so that available VFs
with the corresponding LMACs will attach whereas other, disabled
VFs will fail with the proper error code.
Error signaling (due to improper number of VFs requested) is also moved
from PCI_IOV_INIT() to PCI_IOV_ADD_VF().

This will be reworked when multiple queue sets are enabled but for
now this is the correct behavior of the driver.

Introduce initial support for Cavium's ThunderX networking interface

- The driver consists of three main componens: PF, VF, BGX
- Requires appropriate entries in DTS and MDIO driver
- Supports only FDT configuration
- Multiple Tx queues and single Rx queue supported
- No RSS, HW checksum and TSO support
- No more than 8 queues per-IF (only one Queue Set per IF)
- HW statistics enabled
- Works in all available MAC modes (1,10,20,40G)
- Style converted to BSD according to style(9)
- The code brings lmac_if interface used by the BGX driver to
update its logical MACs state.
