Yes, that is simpler, and the early table then goes through the same
IOMMU flush as every other one, so there is no need to reason about
what an IOMMU can see during boot.  The only cost is that it waits on
the list until the next kernel page table is freed after boot.

I'll send a v2 that way once I have booted it here.
