[PATCH] ARM: 2815/1: Shark: new defconfig, fixes with __io and serial ports 



Patch from Alexander Schulz

This patch brings a new default config file for the shark and
fixes a compilation issue with io addressing and a runtime
problem with the serial ports, where I corrected a wrong
regshift value.
These are all shark specific files so I hope it is ok to
put them in one patch.
