[ARM] 4554/1: replace consistent_sync() with flush_ioremap_region()

Browse Source 
This fixes a regression from around 2.6.18, consistent_sync() will now BUG()
under these circumstances.  The use of consistent_sync() was a hack, replacing
it's usage here with a new function, flush_ioremap_region().
