This patch adds a Kconfig option for SDIO bus support and abstracts
a build subset correspondingly. It's the final patch of fullmac bus
interface refactoring.

          This module adds support for embedded wireless adapters based on

+         Broadcom IEEE802.11n FullMAC chipsets. It has to work with at least
+         one of the bus interface support. If you choose to build a module,
          it'll be called brcmfmac.ko.
