I added the phandle for fw_pinmux and used it as you suggested.
Furthermore added the function gpio similar to your referenced PR.

Hopefully this reflects your intentions.

I just compiled and tested it again, resetting still works with the
added changes.

Have a nice evening everyone and thanks for reviewing this
