ARM: tegra: Add support for TK1-SOM board from Colorado Engineering

The Colorado TK1 SOM is a small form factor board similar to the
Jetson TK1.  The main differences lie in the pinmux, and in that the
PCIe controller is set to use in 4lanes+1lane, rather than 2+2.

The pinmux header here was generated from a spreadsheet provided by
Colorado Engineering using the tegra-pinmux scripts.  The spreadsheet
was converted from v09 to v11 by me.
