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
