Rename I2C and GPIO nodes according to AM33XX TRM. According to
AM33XX TRM device instances are starting from "0" like i2c0, i2c1
and i2c3.

Add pinmux configurations for gpio based keys to am335x-evmsk. In
this patch, only single named mode/state is added and these pins
are configured during pinctrl driver initialization.

Default mode is nothing but the values required for the module during
active state. With this configurations module is functional as
expected.

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

In AM335x EVM tsl2550 ambient light sensor is connected to I2C2 bus.
Add child node inside i2c2 node with i2c slave address.

TAOS tsl2550 sensor is using a two-wire SMBus serial interface.
Reduce I2C2 clock frequency to 100kHz from 400kHz because the
maximum clock frequency of SMBus is 100kHz.

Ideally in common SoC dtsi file should set all modules
to "disabled" state and it should get enabled in respective
EVM/Board dts file as per usage.

This patch sets default status of all modules to "disabled"
state in am33xx.dtsi file. Currently there are no modules
supported as part of Bone and EVM dts support, so care
to add entry "status = "okay"" while adding support for any
module.
