According to Haojian it works, but for sure the MMCI driver *should*
(on the eternal list of SHOULDDO) bail out and return any
-EPROBE_DEFER up to the AMBA bus core properly so it
will be tried again later if this happens.

AFAICT gpio_request() will return -EPROBE_DEFER if the GPIO
cannot be located.
