Conduct some maintenance of the swiotlb code:

	-- Move the code from arch/ia64/lib/ to lib/

	-- Cleanup some cruft (code duplication)

	-- Add support for syncing sub-ranges of mappings

	-- Add support for syncing DMA_BIDIRECTIONAL mappings

	-- Comment fixup & change record

Also, tack-on an x86_64 implementation of dma_sync_single_range_for_cpu
and dma_sync_single_range_for _device.  This makes use of the new
swiotlb sync sub-range support.

In this (third) round, the new location for swiotlb is (again) lib/swiotlb.c.

This set does NOT include the PCI excision that Tony Luck started after the
last round of discussion.

Patches to follow...
