Hi Andrew, this won't break booting as BootROM does not care about
partitions nor naming, it will just go to 0x0 of the NOR and boot it.

The same renaming had already been done:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm64/boot/dts/marvell?h=v5.17&id=a9d9bfcadfb43b856dbcf9419de75f7420d5a225

I can update the commit message if required.
Regards,
Robert
