drm: bridge: samsung-dsim: Implement support for clock/data polarity swap
Implement support for DSI clock and data lane DN/DP polarity swap by
means of decoding 'lane-polarities' DT property. The controller does
support DN/DP swap of clock lane and all data lanes, the controller
does not support polarity swap of individual data lane bundles, add
a check which verifies all data lanes have the same polarity.
This has been validated on an imx8mm board that actually has the MIPI DSI
clock lanes inverted.
