The HLCDC (High LCD Controller) IP supports 4 different output mode (RGB444, RGB565, RGB666 and RGB888) and the pin muxing depends on the chosen RGB mode. Split the pin definition to be able to set the pin config according to the selected mode.

And it depends on the hardware design. So, I think only keep only one pinctrl configuration.
As you pointed out (during our discussion on IRC) sama5d3 SoCs support several pin muxing for LCDDAT pins. I'll take care to define all these pin mux here and select the appropriate ones in sama5d3xdm.dtsi (patch 6) instead of sama5d3_lcd.dtsi (patch 5).
