coreboot tables: Add type-c port info to coreboot table

This change adds type-c port information for USB Type-C ports to the
coreboot table.  This allows depthcharge to know the usb2 and usb3
port number assignments for each available port, as well as the SBU
and data line orientation for the board.

BUG=b:149830546
TEST='emerge-trogdor coreboot' and verify it builds.
TEST='emerge-volteer coreboot chromeos-bootimage' and verify it builds
successfully.  Cherry-pick CL to enable this feature for volteer,
flash and boot volteer2 to kernel, log in and check cbmem for type-c
info exported to the payload:
  localhost ~ # cbmem -c | grep type-c
  Passing conn0 type-c info to payload: usb2:9 usb3:1 sbu:0 data:0
  Passing conn1 type-c info to payload: usb2:4 usb3:2 sbu:1 data:0
