Subject: [PATCH 6/6] staging: tidspbridge: delete unused mmu functions

From: Omar Ramirez Luna <omar.luna@...aro.org>

This should get rid of warnings of the type:

warning: passing argument 1 of '' discards qualifiers from pointer target type
 note: expected 'void *' but argument is of type 'const void *'

Signed-off-by: Omar Ramirez Luna <omar.ramirez@...itl.com>

Intended for 3.7 due to code changes during rc1.
