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.

Add a new LVDS controller driver for sam9x7 which does the following:
- Prepares and enables the LVDS Peripheral clock
- Defines its connector type as DRM_MODE_CONNECTOR_LVDS and adds itself
to the global bridge list.
- Identifies its output endpoint as panel and adds it to the encoder
display pipe
This patch series introduces LVDS controller support for the SAM9X75 SoC. The
LVDS controller is designed to work with Microchip's sam9x7 series
System-on-Chip (SoC) devices, providing Low Voltage Differential Signaling
capabilities.
