The current implementation of the bootloader specification depends on the
hardware name and the name of the device in /dev to match. As the default
hardware name is mciX and the device name is diskY the bootloader spec
cannot be used as is.
This patch implements a way to overwrite the device name similar to what is
possible for the imx-esdhc driver.
