As part of plumbing MemTxAttrs down to the IOMMU translate method,
add MemTxAttrs as an argument to the MemoryRegion valid.accepts
callback. We'll need this for subpage_accepts().
We could take the approach we used with the read and write
callbacks and add new a new _with_attrs version, but since there
are so few implementations of the accepts hook we just change
them all.
