brcm47xx: BGMAC Driver corrections

1) Fix what appears to be a logic error in bgmac_phy_advertise.

2) Fix bgmac_ioctl to use passed phy_id; needed for switch-robo
interface w/ the driver to work correctly.  I still have the issue
with the interface always being HD when the speed/duplex is set
manually (e.g., echo "100FD" > /proc/switch/eth0/port/N/media).
