KVM: arm64: Rename 'host_kvm' to 'host_mmu'

Browse Source 
In preparation for introducing VM and vCPU state at EL2, rename the
existing 'struct host_kvm' and its singleton 'host_kvm' instance to
'host_mmu' so as to avoid confusion between the structure tracking the
host stage-2 MMU state and the host instance of a 'struct kvm' for a
protected guest.
