brcmfmac: Dynamically register a protocol layer.
BCDC is the default protocol layer and being called directly. This patch installs the functions for this layer dynamically. This allows new protocols to be added and selected dynamically depending on the hw capabilties. As currently only BCDC is supported this is always the installed protocol.
