driver/ec/ps8751: Probe EC and register for TCPC FW update operations

TCPC FW update operations are registered statically during the board
setup. With octopus supporting multiple USB-C topologies, allow the
VbootAuxFw driver to probe EC and register for the TCPC FW update
operations.

BUG=b:128820536,b:119046668
BRANCH=None
TEST=Boot to ChromeOS. Ensure that different TCPC topologies are handled
as expected.
