honeybuns: Enable USB-EP support

This CL adds configs/structs required for USB-EP support for both
quiche and gingerbread. This CL also adds usbc support code to RO so
that Rd is being presented on both CC lines in RO.

In addition, there is some clean up for I2C port names and the debug
gpio utility function.

BUG=b:172493899
BRANCH=None
TEST=tested on quiche and verified that the USB-EP was enumerated
