ARM: KVM: Move CP15 array into the CPU context structure
Continuing our rework of the CPU context, we now move the CP15 array into the CPU context structure. As this causes quite a bit of churn, we introduce the vcpu_cp15() macro that abstract the location of the actual array. This will probably help next time we have to revisit that code.
