Follow Peter's review I've split this into a several patches as there
are some other fixes that should be made to other EL2 times that
shouldn't be rolled together.

v2
  - split machine enabling into patches
  - rename IRQ
  - use CP_ACCESS_TRAP_UNCATEGORIZED for UNDEF cases

v1
  - improve GTIMER docs
  - fix gt_recalc bug
  - address review comments for the main patch
  - cc qemu-stable (no rush for 9.2.0)

The following still need review:

  hw/arm: enable secure EL2 timers for sbsa machine
  hw/arm: enable secure EL2 timers for virt machine
  target/arm: implement SEL2 physical and virtual timers
  target/arm: ensure cntvoff_el2 also used for EL2 virt timer

Alex.
