Until now the key modifier was being read from 'hwid_n' device tree
entries, but now those entries reflect the environment HWID, which
could be temporarily overriding the fuse HWID.
Ensure the key modifier is generated from the new 'hwid_fuse_n'
device tree entries created by U-Boot with the contents of the
fuse HWID, just as U-Boot does to encrypt/decrypt the environment.
