Adds the setup/start logic for the ctrl vNIC. This vNIC is used by
the PMD and flower firmware application as a communication channel
between driver and firmware. In the case of OVS it is also used to
communicate flow statistics from hardware to the driver.
A rte_eth device is not exposed to DPDK for this vNIC as it is strictly
used internally by flower logic.
Because of the add of ctrl vNIC, a new PCItoCPPBar is needed. Modify the
related logics.
