t132: Add TTB_BUFFER to resource reserved

TTB_BUFFER holds the MMU tables. Thus, this memory needs to be preserved while
performing a wipe in depthcharge. Hence, marking it as reserved

BUG=None
BRANCH=None
TEST=Compiles successfully and boots upto depthcharge. Error wiping memory
tables is fixed.
