    tegra132: Add Trust Zone register access
    
    The Trust Zone carveout registers are only accessible using
    a secure access mode. The AVP runs as non-secure all the time.
    In EL3 the CPU is in secure mode, but when the MMU is enabled
    the page tables dictate if accesses to certain regions are
    secure or not. However, ramstage is currently being loaded
    into non-secure memory and the page tables will live in
    non-secure memory as well. Therefore, handle all these
    cases by providing global state which mirrors the TZ
    register.
    
    BUG=chrome-os-partner:30782
    BRANCH=None
    TEST=Built and ran through ramstage with the MMU enabled
         Resources are read and set accordingly.
