ARM: dts: cm-t335: add initial support 

Add basic support for CompuLab cm-t335 module based on AM335X SoC.

CM-T335 is a tiny computer-on-module (CoM) / system-on-module (SoM)
The module is built around the Texas Instruments Sitara AM3352/4
system-on-chip.

The CPU is supplemented with up-to 512MB DDR3 and up-to 1GB of on-board
NAND storage, WiFi connected to SPI, Bluetooth, Analog audio, Gigabit
Ethernet, CAN bus.

Current patch adds support:
UART0 and GPIO LED

Detailed description can be found at the module site:
