There's a lot of code in the brcmfmac part of the driver that tries to
re-implement SDIO stack. In particular, the code removed by this patch
registers a pci_driver for SDIO controller and then the brcmfmac
driver accesses the WiFi device attached to that SDIO controller by
means of custom re-implementation of SDHC.
