Guybrush: Set up custom Vbus source detection
In the USB common code, PPCs will always be given priority over TCPCs
for detecting whether sourcing is enabled. However, with FRS enabled
the PPC cached flags no longer accurately reflect whether we're
sourcing. Therefore, set up a custom board function which may query the
most appropriate chip, though for now set it up for the same component
used by the Vbus discharge code.
