ARM: dts: imx31: add LogicPD MX31Lite board description

The added DTS contains a combined description of LogicPD MX31 Lite
SoM devices, peripherals are routed to ports on a baseboard:
* PATA controller,
* SD/MMC controller,
* 2 GPIO LEDs,
* UART controllers,
* Freescale MC13783 MFD connected over SPI,
* SMSC LAN9117,
* ST Micro NAND SLC, 64 MiB,
* Intel NOR flash, 16 MiB.
