Add a minimal board dts file for EXYNOS4412 based FriendlyARM's TINY4412 board. This patch including adds the node to support peripherals like UART, SD card on SDMMC2 port, and this patch adds GPIO connected LEDS and configure its properties like following: LED1: use 'heartbeat' trigger, blinking while the board is running. LED4: use 'mmc0' trigger, on when mmc0 is accessing. LED2 and LED3 can be controlled from userspace.
