swiotlb: allow architectures to override swiotlb pool allocation

Browse source

Impact: generalize swiotlb allocation code

Architectures may need to allocate memory specially for use with
the swiotlb.  Create the weak function swiotlb_alloc_boot() and
swiotlb_alloc() defaulting to the current behaviour.
