Subject: [PATCH 1/2] Revert "device property: Keep secondary firmware node secondary by type"

While the commit d5dcce0c414f ("device property: Keep secondary firmware
node secondary by type")
describes everything correct in its commit message the change it made does
the opposite and original commit c15e1bdda436 ("device property: Fix the
secondary firmware node handling in set_primary_fwnode()") was fully
correct. Thus, revert the former one here and improve documentation in
the next patch.

Fixes: d5dcce0c414f ("device property: Keep secondary firmware node secondary by type")
