Make flatview_extend_translation() take a MemTxAttrs argument

Browse Source 
As part of plumbing MemTxAttrs down to the IOMMU translate method,
add MemTxAttrs as an argument to flatview_extend_translation().
Its callers either have an attrs value to hand, or don't care
and can use MEMTXATTRS_UNSPECIFIED.
