hw/arm/smmu: Introduce smmu_iotlb_inv_asid_vmid

Browse source 
Soon, Instead of doing TLB invalidation by ASID only, VMID will be
also required.
Add smmu_iotlb_inv_asid_vmid() which invalidates by both ASID and VMID.

However, at the moment this function is only used in SMMU_CMD_TLBI_NH_ASID
which is a stage-1 command, so passing VMID = -1 keeps the original
behaviour.
