It's normally up to the kernel driver to know about the firmware
file names and the order of trying the possible fallbacks, which
is exactly why I originally asked to not rely on the property
from dtb.
If you want a symlink in linux-firmware, that would go the other
way, pointing the old filename to the new location.
