It was asserted that the "/delete-property/ VBAT-supply;" that we
needed to do in the rt5682s dts fragment was ugly. Let's change up all
the trogdor device trees to make it explicit which version of "rt5682"
we have and avoid the need for the "delete-property".

As a side effect, this nicely gets rid of the need for a delete-node
in coachz, which doesn't use "rt5682" at all.

A few notes:
- This doesn't get rid of every "/delete-node/" in trogdor, just the
  one that was used for rt5682s.
- Though we no longer have any "/delete-node/", we do still override
  the "model" in the "sound" node in one case (in pompom) since that
  uses the "2mic" sound setup.

This is validated to produce the same result (other than a few
properties being reordered) when taking the dtbs generated by the
kernel build and then doing:

  for dtb in *trogdor*.dtb; do
    dtc -I dtb -O dts $dtb -o out/$dtb.dts;
  done
