This is the second take on this series aiming at reducing the abuse of
the kvm_vcpu_arch structure, and moving things info the per-CPU
context.

* From v1 [1]:

- Fixed the per-CPU accessor outside of the hypervisor code (the
protected case is... interesting)

- Spelling fixes

- Collected RBs

- Rebased on kvmarm-6.9
