KVM: arm64: Compute MDCR_EL2 at vcpu_load()

Browse source

KVM has picked up several hacks to cope with vcpu->arch.mdcr_el2 needing
to be prepared before vcpu_load(), which is when it gets programmed
into hardware on VHE.

Now that the flows for reprogramming MDCR_EL2 have been simplified, move
that computation to vcpu_load().
