Initial C1 board support

Mainly based on Freescale sabresd board with pinout modifications and features on/off

This only adds supports for the main functionality; booting off an SD card.
I2C, Ethernet, LVDS and other is still not supported.

Manually added machine ID; this should probably go away once the upstream file is pulled
