usb: typec: fsa4480: Add support to swap SBU orientation

On some hardware designs the AUX+/- lanes are connected reversed to
SBU1/2 compared to the expected design by FSA4480.

Made more complicated, the otherwise compatible Orient-Chip OCP96011
expects the lanes to be connected reversed compared to FSA4480.

* FSA4480 block diagram shows AUX+ connected to SBU2 and AUX- to SBU1.
* OCP96011 block diagram shows AUX+ connected to SBU1 and AUX- to SBU2.

So if OCP96011 is used as drop-in for FSA4480 then the orientation
handling in the driver needs to be reversed to match the expectation of
the OCP96011 hardware.

Support parsing the data-lanes parameter in the endpoint node to swap
this in the driver.

The parse_data_lanes_mapping function is mostly taken from nb7vpq904m.c.
