net: ethernet: bgmac: Add platform device support
The bcma portion of the driver has been split off into a bcma specific driver. This has been mirrored for the platform driver. The last references to the bcma core struct have been changed into a generic function call. These function calls are wrappers to either the original bcma code or new platform functions that access the same areas via MMIO. This necessitated adding function pointers for both platform and bcma to hide which backend is being used from the generic bgmac code.
