ARM: highbank: use common debug_ll_io_init

Commit Message

Rob Herring Nov. 8, 2012, 12:09 a.m. UTC

From: Rob Herring <[e-mail]>

Remove the platform static mapping code for uart and use the common
debug_ll_io_init function.

Signed-off-by: Rob Herring <[e-mail]>

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