Subject: unexport swiotlb_active v2

Hi all,

this little series removes the last swiotlb API exposed to modules.

Changes since v1:
- add a patch from Juergen to export if the e820 table indicates Xen PV
PCI is enabled
- slightly reorganize the logic to check if swiotlb is needed for
Xen/x86
- drop the already merged nouveau patch

Let me second this request. My dynamic SWIOTLB patch series also has a
dependence on this.
