commit 668761ac01d6f5a36b8e5a24d4e154550e2c4c3b
Author: Hante Meuleman <meuleman@xxxxxxxxxxxx>

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.
