From: Quentin Schulz <quentin.sch...@theobroma-systems.com>
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 only define the spl_boot_devices array in
the appropriate SoC file in an upcoming commit.
