plankton: HPD over USB PD.
HPD needs to be transported over USB PD as both SBU lines are consumed
for differential AUX signalling.
This CL does the following:
1. Enables GPIO DPSRC_HPD as interrupt.
2. Sends debounced HPD across CC via the SVDM DP status message.
3. Adds polling for GPIO_DBG_20V_TO_DUT_L as it shares the same
interrupt as DPSRC_HPD.
4. Configures DP redriver in presence of HPD high.

BRANCH=none
BUG=chrome-os-partner:33132,chrome-os-partner:33761
TEST=manual,
1. Connect samus -> plankton via type-C
2. Connect plankton -> DP monitor via displayport
See initial SVDM discovery on samus console
See EDID information
See SVDM status message correct when plug/unplug DP cable from plankton
3. Press 'CHARGING_20V_TO_DUT_L' button and see below on plankton console.
Button 8 = 0
