It is possible to boot U-Boot proper from a different storage medium
than the one used by the BOOTROM to load the SPL. This information is
stored in the u-boot,spl-boot-device Device Tree property and is
accessible from U-Boot proper so that it has knowledge at runtime where
it was loaded from.
Let's add support for this feature for rk3588 the same way it was done
for px30 and rk3399.
