[PATCH v2] mx35_3ds: Add the TFT display to the board file

[Michael Grzeschik]

From: Juergen Beisert <jbe at pengutronix.de>

Add the personality board's display to the board file. Used display is:

Manufacturer: CTP
Type: CLAA070LC0ACW

This is a 800 x 480 wide display with 27 MHz pixel clock and 60 Hz refresh
rate with 18 bit data interface. Sync is based on DE only.

v1 -> v2
	* removed superfluous comments
	* added S-o-b

The power for the display is driven by the mc9s08.

Since patch 3aa519797e79ed4d85cd6604cdf642f99d4bb2ef in the barebox
bootloader we toggle the power to the LCD by software.
