Wed Nov 7 19:09:01 EST 2012
From: Rob Herring <rob.herring at calxeda.com>
Remove the platform static mapping code for uart and use the common
debug_ll_io_init function.
Signed-off-by: Rob Herring <rob.herring at calxeda.com>

This is dependent on arm-soc/devel/debug_ll_init and
arm-soc/calxeda/ecx-2000 branches.
