tx27stk5: add board init support for KaRo TX27 CPU module

This patch adds support for a KaRo TX27 CPU module on a StarterkitV base board.
The register settings have been extracted from a RedBoot distribution
that is distributed along with the hardware by KaRo.

This setup has been tested with a JTAGKey. The testing has been focussed
on loading a program into memory and start execution.
Although the flash seems to be correctly detected, no effort has been put
in testing the NAND programming yet.
