iommu/vt-d: Deduplicate cache_tag_flush_all by reusing flush_range
The logic in cache_tag_flush_all() to iterate over cache tags and issue
TLB invalidations is largely duplicated in cache_tag_flush_range(), with
the only difference being the range parameters.
Extend cache_tag_flush_range() to handle a full address space flush when
called with start = 0 and end = ULONG_MAX. This allows
cache_tag_flush_all() to simply delegate to cache_tag_flush_range()
