- Avoid add/sub on vcpu pointer in world-switch
Changes since v1-v4:
- Get virtual IRQ number from DT
- Simplify access to cntvoff and cntv_cval
- Remove extraneous bit clearing
- Abstract timer arming/disarming to improve code readability
- Context switch CNTKCTL across world-switches
- Add CPU hotplug notifier
