ANDROID: KVM: arm64: smmuv3: Split stage-1 config

As the driver can use both stage-1 and stage-2, hold their configs in
the hyp_arm_smmu_v3_device struct instead of just stage-2 and
initialize both of them at boot and the hypervisor driver would
choose the correct configuration based on the requested domain
type.
