ARM: dts: Amazon Kindle Fire (first generation) codename kc1 basic support 

The Amazon Kindle Fire (first generation) codename kc1 is a tablet that was
released by Amazon back in 2011. It is using an OMAP4430 SoC GP version.

This adds devicetree support for the device, with only a few basic features
supported, such as debug uart, i2c and internal emmc.
