BOOTROM sets a bit in a CPU register so that the software can know from where the first stage bootloader was booted. One use case for this is to specify the default loading medium for U-Boot proper to match the one used by the BOOTROM to load the SPL (same-as-spl in u-boot,spl-boot-order).
Let's create the mapping between BOOTROM value and Device Tree node names for MMC devices.
