I've been experimenting with modular IOMMU drivers on top of the
probe-deferral stuff[1], and the ARM SMMU driver in particular demands a
whole pile of exports. I thought I'd throw this one out now since nearly
all the other of_* functions are exported already, but I'm quite happy
to sit on it if you'd prefer to wait for a concrete in-tree need (it'll
be a while yet).
