In preparation of moving spl_perform_fixups to spl-boot-order.c, let's simplify the logic around mapping the BOOT_DEVICE_x enum index to a DT node by using an instantiated array of chars instead of creating a new data structure on the fly.
This will make it easier to factor out the code handling the SPL boot medium detection by having spl_decode_boot_device common to all SoCs.
