i wanted to use this method in depthcharge but it was rejected there.
see b/149883933 and discussions on related patches.

there is no patch that does this currently, this will be a new functionality.
the way this was addressed in depthcharge was to put the port config into
the config and use a variant specific config given that the port mapping
is static topology info.

coreboot should be less problematic. i think you'll have to walk
the device tree to use the same info that's passed to the kernel
to plumb up USB-C. i think you'll need to get sbu_orientation
from there as well to support DP.
