virtio: Define and use per-architecture "pfn shift" constants

Both sides of the virtio interface must agree about how big a pfn really is.
This is particularly an issue on architectures where the page size is
configurable (e.g. PowerPC, IA64) -- the interface must be independent of
PAGE_SHIFT.

This patch should have no functional effect on x86 or ia64, but an ack from the IA64 guys
would be good because I'm not clear on their page size requirements.

This is missing a fix for virtio-balloon.

Anthony Liguori
