ARM: dts: Add am335x-evmsk.dts 

Add AM335X EVM-SK device tree source (am335x-sk.dts) file to use
the am33xx.dtsi SoC file, along with the memory node information.

Also adds support for tps65910 regulator and lis331dlh accelerometer.
Following drivers/functionality were tested on AM335x-EVM-SK.
* I2C
* TPS65910 regulators
* lis331dlh accelerometer
