The ports definition currently defined in the usb-switch.yaml
fits standards devices which are either recipient of altmode
muxing and orientation switching events or an element of the
USB Super Speed data lanes.
This doesn't necessarely fit combo PHYs like the Qualcomm
USB3/DP Combo which has a different ports representation.
Move the ports definition to a separate usb-switch-ports.yaml
and reference it next to the usb-switch.yaml, except for
the Qualcomm USB3/DP Combo PHY bindings.

An array of physical data lane indexes. Position determines how

lanes are connected to the redriver, It is assumed the same order
|
|
is kept on the other side of the redriver.
|
|
Lane number represents the following
|
|
- 0 is RX2 lane
|
|
- 1 is TX2 lane
|
|
- 2 is TX1 lane
|
|
- 3 is RX1 lane
|
|
The position determines the physical port of the redriver, in the
|
|
order A, B, C & D.
