Since v1:
- Addressed rth's review comments

Omnibus series of ARM-related patches (noticed during the
"split accel" PoC work).

- Usual prototypes cleanups
- Check TCG for EL2/EL3 features (and not !KVM or !HVF)
- Improve HVF debugging
- Correct HVF 'dtb_compatible' value for Linux
- Fix HVF GTimer frequency (My M1 hardware has 24 MHz)
  (this implies accel/ rework w.r.t. QDev vCPU REALIZE)
- Expand functional tests w.r.t. HVF

Regards,

Phil.
