Early Armadillo 500 support

Ok! Now I am ready to post the first official Early Atmark Armadillo 500 developing board support patch!

This patch add the Armadillo 500 initial support. Enabling the mxc uart console via make gconfig (by default using make armadillo500_defconfig) we can see the console output through Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0).

To see debug strings on the console you have to apply the patch "Clock ipg_clk/ipg_per_clk synchronization" due to resolve clock the synchronization issue.

Patches attached because of changes made by this blog to the code style. (Indentation, ...)
