eve: Add support for anx3429 tcpc low power mode

Browse Source 
Added interrupt handler for CABLE_DET signal on both port 0/1. This
allows us to define CONFIG_USB_PD_TCPC_LOW_POWER.

BUG=chrome-os-partner:63067
BRANCH=none
TEST=Connected USB mouse, keyboard and USB stick to both ports and
verified the devices were recognized and attached properly. Verified
that ports 0/1 always worked with blackcat typeC charger.
