Jean-Christophe PLAGNIOL-VILLARD 873910050e at91: implement clock framework
this implementation is based on linux one (v2.6.35-rc5-76-gd0c6f62)
it will calculate all the clock dynamically instead of statictly
this will use also the new clock framework

it will also print the clock status after the console init
