drm: Add helpers for setting up an array of dma_fence dependencies.
I needed to add implicit dependency support for v3d, and Rob Herring
has been working on it for panfrost, and I had recently looked at the
lima implementation so I think this will be a good intersection of
what we all want and simplify our scheduler implementations.
v2: Rebase on xa_limit_32b API change, and tiny checkpatch cleanups on
the way in (unsigned int vs unsigned, extra return before
EXPORT_SYMBOL_GPL)
