If the GPIOs used by the MMCI driver are not registered yet when the driver is probe()d, they can't be used. This happens if the mmci driver is probed before the respective GPIO controller (e.g. on the LPC32xx EA3250 board, the PCA9532 GPIO controller would be initialized via DT after mmci). Therefore, we defer mmci in this case. Signed-off-by: Roland Stigge <redacted>
