Add support for the amac found in the Broadcom Northstar2 SoC to the
bgmac driver.  This necessitates adding support to connect to an
externally defined phy (as described in the device tree) in the driver.
These phy changes are in addition to the changes necessary to get NS2
working.

This does not apply cleanly to the net-next, please respin.
