Volteer: Add support for FRS to C1
Add support to C1, assign the gpio to put the PPC in FRS mode and add the config options. Volteer boards need the SYV682B rework to support FRS, but this will not break existing boards. FRS will be enabled but fail, and enter ErrorRecovery, enter Unattached.SNK, or successfully FRS depending on the situation. Volteer HW can supply 3A per port, so changes to reserve the FRS current aren't needed to enable it on Volteer. BUG=b:148144711 TEST=Check that FRS is functional. FRS devices should not re-enumerate after adapter power is removed. Test with the SYV682B and using both the PS8815 and RT1715 TCPCs.
