A common software error when it comes to page table code is missing TLB
maintenance. Add some checks to the io-pgtable-fast code to detect when
an address that might be stale in the TLB is being re-used. This can be
accomplished by writing a "stale TLB" flag value to the reserved bits of
the PTE during unmap and then removing the flag value when the TLBs are
invalidated (by sweeping the entire page table). That way, whenever we
map we can know that there might be a stale TLB in the location being
mapped into if it contains the "stale TLB" flag value.

There are certain use cases where it might be necessary to leave the
IOMMU's configuration clocks on. This might happen in places where an
IOMMU's clocks might not be known. A good example of this would be a
test library that needs to be able to do TLB invalidation from atomic
context. It would need to enable clocks up front (outside of atomic
context) and leave them on for the duration of the test.

The upcoming "fast" DMA mapper will need to take control of TLB
invalidation. Doing so allows us to perform fewer TLB invalidation
operations since the DMA mapper layer has more knowledge about when
"stale" TLB entries might actually become a problem, so it can do TLB
invalidation much less frequently. Implement the tlbi_domain op for
this purpose.
