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. Backports commit 452ef8cb8c7b06f44a30a3c3a54d3be82c4aef59 from qemu
