    brcmfmac: define and use platform specific data for SDIO.

    This patch adds support for platform specific data for SDIO
    fullmac devices. Currently OOB interrupts are configured by Kconfig
    BRCMFMAC_SDIO_OOB but that is now determined dynamically by checking
    availibility of platform data.
