mainboard/google/kahlee: Update overcurrent pins
The overcurrent pins on kahlee weren't mapped correctly, causing
the USB-A port to stop working.
None of the EHCI only ports are used for external connectors, so all
of the overcurrent pins should go to the XHCI connections. This is
also true of the Grunt board.
On Grunt, this also means that we don't need OC3, as it doesn't map
to anything in the XHCI controller, as it's coming from an internal
hub.
BUG=b:70636233
TEST=Build & boot Kahlee, verify USB-A port is working again.
