OcteonTX2 BPHY RFOE netdev driver initial version

commit 1b529ac5f6b2a45a3aec5c9aee1aa831ca6eea61 from
git@git.assembla.com:cavium/WindRiver.linux.git

The BPHY RFOE netdev driver handles the packets such as eCPRI control
data, PTP and other ethernet packets received from/sent to BPHY RFOE
MHAB in Linux kernel. All other packets (ROE, eCPRI non-control)
received/sent are handled by ODP application in user space. The ODP
application initializes the JDT/MBT/PSM-queues to process the Rx/Tx
packets in netdev and shares the information through driver ioctl.
The Rx/TX notification will be sent to netdev using one of the PSM GPINT.
