mb/google/volteer: Add support for passive USB-C daughterboard 

The USB-C SBU and HSL orientation configuration depends on the USB
daughterboard used on the system. This patch adds an additional
configuration for supporting passive USB daughterboards using "probe"
directives to select the appropriate configuration at runtime.

BUG=b:158673460
TEST=verified active USB DBs enumerate at USB3 speeds in linux
