[PATCH v2] ARM: highbank: fix debug uart virtual address for LPAE

From: Rob Herring <rob.herring at calxeda.com>

Section entries are 2MB on LPAE, so the DEBUG_LL virtual address must
have the same offset in the 2MB section as the physical address. This
fixes async external aborts when DEBUG_LL is enabled on Midway.
