octopus: remove unused TCPC re-driver power code
octopus: remove unused TCPC re-driver power code

We had a hardware revision that used GPIO03 from the PS8751 as the
enable signal for the TypeA USB re-driver power regulator. This prove to
not work especially when the TCPC came back from low power mode.

The hardware change has been reverted and now we are removing the
firmware support for this change.

BRANCH=octopus
BUG=b:111406013,b:117656946
TEST=builds. Version 2.24 (released 10/30) of sub-board schematics
mark the stuffing options to have the TCPC control the power as DNS.
Version 2.2 was never officially released that had the faulty
hardware circuit. Only a single spin of sub-boards had this circuit and
they have been reworked.
