merge pci-base_32.c and pci-nommu_64.c into pci-nommu.c
Their code were made the same, so now they can be merged.

In the very same way i386 do, we use WARN_ON functions
in map_simple and map_sg.

To make the code usable in i386, where we have high memory mappings,
we drop te virt_to_bus(sg_virt()) construction in favour of sg_phys.

This patch adds flush_write_buffers() in some functions of pci-nommu_64.c
They are added anywhere i386 would also have it. This is not a problem
for x86_64, since flush_rite_buffers() an nop for it.

This patch implements mapping_error for pci-nommu_64.c.
It takes care to keep the same compatible behaviour it already
had. Although this file is not (yet) used for i386, we introduce
the i386 version here. Again, care is taken, even at the expense of
an ifdef, to keep the same behaviour inconditionally.

This functions are now called conditionally on their
existence in the struct. So just delete them, instead
of keeping an empty implementation.

This patch renames the include file asm-x86/iommu.h to asm-x86/gart.h to make
clear to which IOMMU implementation it belongs. The patch also adds "GART" to
the Kconfig line.
