Matthew Wilcox pointed out that swiotlb.c implements a generic
interface that is not tied to just PCI. Remove includes of
<linux/pci.h>, <asm/pci.h>. Fix comments and printk() messages
to no longer refer to PCI.

Change comment at top of swiotlb.c to reflect that the code is shared
with EM64T (i.e. Intel x86_64). Also add an entry for myself so that
if I "broke it", everyone knows who "bought it"... :-)

The current implementation of sync_single in swiotlb.c chokes on
DMA_BIDIRECTIONAL mappings. This patch adds the capability to sync
those mappings, and optimizes other syncs by accounting for the
sync target (i.e. cpu or device) in addition to the DMA direction of
the mapping.

This patch implements swiotlb_sync_single_range_for_{cpu,device}. This
is intended to support an x86_64 implementation of
dma_sync_single_range_for_{cpu,device}.

The implementations of swiotlb_sync_single_for_{cpu,device} are
identical. Likewise for swiotlb_syng_sg_for_{cpu,device}. This patch
move the guts of those functions to two new inline functions, and
calls the appropriate one from the bodies of those functions.

The swiotlb implementation is shared by both IA-64 and EM64T. However,
the source itself lives under arch/ia64. This patch moves swiotlb.c
from arch/ia64/lib to lib/ and fixes-up the appropriate Makefile and
Kconfig files. No actual changes are made to swiotlb.c.
