In order to add support for substream ID, move the context descriptor code
into a separate library. At the moment it only manages context descriptor
0, which is used for non-PASID translations.

One important behavior change is the ASID allocator, which is now global
instead of per-SMMU. If we end up needing per-SMMU ASIDs after all, it
would be relatively simple to move back to per-device allocator instead
of a global one. Sharing ASIDs will require an IDR, so implement the
ASID allocator with an IDA instead of porting the bitmap, to ease the
transition.

Hi Jean-Philippe,

This would have been easier to review if split into a 'move' and additional
patches actually making the changes described.

Superficially it looks like there may be more going on in here than the
above description suggests.  I'm unsure why we are gaining 
the CFGI_CD_ALL and similar in this patch as there is just to much going on.

Ok I'll try to split this

Thanks,
Jean
