dt-bindings: display: bridge: add sam9x75-lvds binding

Add the 'sam9x75-lvds' compatible binding, which describes the Low Voltage
Differential Signaling (LVDS) Controller found on some Microchip's sam9x7
series System-on-Chip (SoC) devices. This binding will be used to define
the properties and configuration for the LVDS Controller in DT.

+description:
+  The Low Voltage Differential Signaling Controller (LVDSC) manages data
+  format conversion from the LCD Controller internal DPI bus to OpenLDI
+  LVDS output signals. LVDSC functions include bit mapping, balanced mode
+  management, and serializer.
