Add a very basic mmu-less support for coldfire m548x family. This is perhaps also valid for m547x family. The port comprises the serial, tick timer and reboot support. The gpio part compiles but is empty. This gives a functional albeit limited linux for the m548x coldfire family. This has been tested on a Freescale M548xEVB Lite board with a M5484 processor and the default dbug monitor.
