This series of patches add support for the Broadcom BCM53134 managed Ethernet switch device, as well as some extra additions.

The additions now only cover the MDIO interface part of the device. The
BCM53134 device is also controllable through the SPI interface, but for now I don't have the hardware available to test this interface. The functionality in the b53_common sources should be the same though.
