Rémi Denis-Courmont b6ad6062f1 target/arm: add MMU stage 1 for Secure EL2
This adds the MMU indices for EL2 stage 1 in secure state.

To keep code contained, which is largelly identical between secure and
non-secure modes, the MMU indices are reassigned. The new assignments
provide a systematic pattern with a non-secure bit.
