PATCH 1/1 video/lcd: add new driver of LCD controler for Atmel new SoC

The Atmel new SoC (at91sam9x5 series and at91sam9n12) add a totally different LCD controller. Add this new driver is used to support it.

Using CONFIG_ATMEL_HLCD (distinguish with CONFIG_ATMEL_LCD) to enable this in board configuration file.
