iommu/arm-smmu: Simplify VMID and ASID allocation
We only use ASIDs and VMIDs to identify individual stage-1 and stage-2
context-banks respectively, so rather than allocate these separately
from the context-banks, just calculate them based on the context bank
index.
Note that VMIDs are offset by 1, since VMID 0 is reserved for stage-1.
This doesn't cause us any issues with the numberspaces, since the
maximum number of context banks is half the minimum number of VMIDs.
