tcg: Split out target/arch/cpu-param.h For all targets, into this new file move TARGET_LONG_BITS, TARGET_PAGE_BITS, TARGET_PHYS_ADDR_SPACE_BITS, TARGET_VIRT_ADDR_SPACE_BITS, and NB_MMU_MODES. Include this new file from exec/cpu-defs.h. This now removes the somewhat odd requirement that target/arch/cpu.h defines TARGET_LONG_BITS before including exec/cpu-defs.h, so push the bulk of the includes within target/arch/cpu.h to the top. Backports commit 74433bf083b0766aba81534f92de13194f23ff3e from qemu

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. Backports commit 452ef8cb8c7b06f44a30a3c3a54d3be82c4aef59 from qemu
