  Log:
  - Do a better job of handling any Dependent Functions (aka DPFs) that appear
    in the _PRS or _CRS of link devices.  If faced with multiple DPFs in a
    _PRS, we just use the first one.  We assume that if _CRS has DPF tags they
    only contain a single set since multiple DPFs wouldn't make any sense.  In
    practice, the only DPFs I've seen so far for link devices are that the one
    IRQ resource is surrounded by a DPF tag pair for no apparent reason, and
    this should handle that case fine now.
  - Only allocate link structures for IRQ resources for link devices rather
    than allocating a link structure for every resource.
