target/arm: Add mmu_idx for EL1 and EL2 w/ PAN enabled
To implement PAN, we will want to swap, for short periods
of time, to a different privileged mmu_idx. In addition,
we cannot do this with flushing alone, because the AT*
instructions have both PAN and PAN-less versions.
Add the ARMMMUIdx*_PAN constants where necessary next to
the corresponding ARMMMUIdx* constant.
