The DRM subsystem graphics drivers require more granular definition of the connection between display drivers and panels, and a proper panel compatible. This utilizes the bindings merged to the DRM subsystem to properly define the display on the NSPIRE devices. We also do away with the undocumented DT binding "lcd-type". We add both the clocks to the CLCD block so the driver have full control over its clocking.
