target-arm: Use correct mmu_idx for unprivileged loads and stores

The MMU index to use for unprivileged loads and stores is more
complicated than we currently implement:
 * for A64, it should be "if at EL1, access as if EL0; otherwise
   access at current EL"
 * for A32/T32, it should be "if EL2, UNPREDICTABLE; otherwise
   access as if at EL0".

In both cases, if we want to make the access for Secure EL0
this is not the same mmu_idx as for Non-Secure EL0.
