    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.
