S-Video, Ethernet, SD/MMC, keyboard, camera, SPI, I2C, USB and
JTAG interface.

This patch adds the basic DT support for devkit8000. At this time, Information
of twl4030 (PMIC), MMC1, I2C1 and leds are added.

 -This patch is based on top of kernel 3.8-rc5.

 -Tested on Devkit8000.

For V3:
 - Remove pin mux as done at device boot time by default.

For V2:
 - Change model name as "TimLL OMAP3 Devkit8000"
 - Change compatible as "timll,omap3-devkit8000"
 - Doing i2c1 pinmux default with pinctrl-single driver instead of i2c1
   driver probe time.
