Here's a few cleanups and fixes for 5.6, all around our debug and PMU ID register emulation: 1) Missing RES1 bit in DBGDIDR 2) Limiting PMU version to v8.1 3) Limiting debug version to ARMv8.0 4) Support for ARMv8.4-PMU (1) was reported by Peter, (2) had a patch from Andrew Murray on the list, but it's been a while since he was going to rebase and fix it, so I did bite the bullet. (3) is needed until we implement the right thing with NV. (4) was too easy not to be done right away. Patch #2 is a cleanup that helps the following patches. Unless someone objects, I'd like to take this into 5.6 (except maybe for the last patch).
