[media] dt: bindings: Add lane-polarity property to endpoint nodes

Browse source 
Add lane-polarity property to endpoint nodes. This essentially tells that
the order of the differential signal wires is inverted.

- link-frequencies: Allowed data bus frequencies. For MIPI CSI-2, for
instance, this is the actual frequency of the bus, not bits per clock per
lane value. An array of 64-bit unsigned integers.
- lane-polarities: an array of polarities of the lanes starting from the clock
lane and followed by the data lanes in the same order as in data-lanes.
Valid values are 0 (normal) and 1 (inverted). The length of the array
should be the combined length of data-lanes and clock-lanes properties.
If the lane-polarities property is omitted, the value must be interpreted
as 0 (normal). This property is valid for serial busses only.
