Puff: Disable USB-C DRP auto-toggle and lower power mode
Puff: Disable USB-C DRP auto-toggle and lower power mode

The ANX3447 TCPC DRP auto-toggle does not appear to be reliable.
Disable the DRP auto-toggle (the state machine falls back
to trying SNK/SRC alternatively).
As a separate issue, doe to a state machine error, the
low power TCPC mode also has to be disabled.

BUG=b:155253129
TEST=Unplug and plug various type-C USB devices into puff board.
BRANCH=none
