This reverts commit 29f6589140a10ece8c1d73f58043ea5b3473ab3e. After that patch landed I find that my kernel log on rk3288-veyron-minnie and rk3288-veyron-speedy is filled with: brcmfmac: brcmf_sdio_bus_sleep: error while changing bus sleep state -110 This seems to happen every time the Broadcom WiFi transitions out of sleep mode. Reverting the commit fixes the problem for me, so that's what this patch does. Note that, in general, the justification in the original commit seemed a little weak. It looked like someone was testing on a SD card controller that would sometimes die if there were CRC errors on the bus. This used to happen back in early days of dw_mmc (the controller on my boards), but we fixed it. Disabling a feature on all boards just because one SD card controller is broken seems bad.
