  Log:
  - Add support for link devices where _CRS just outright fails to execute.
    For such devices, we require _PRS to exist and we warn if any of the
    resources in _PRS are not IRQ resources (since we'll have no way of knowing
    which of those resources to use without a working _CRS).  When it does
    come time to set resources, we build up a resource buffer from scratch
    as we do for devices with _CRS that only have IRQ resources.
  - Fix a bug with setting extended IRQ resources where we set the IRQ value
    in the wrong resource structure meaning that whichever IRQ was listed in
    _PRS was used instead.  This might fix some weird issues on certain boxes
    where IRQs > 16 don't seem to work when using ACPI.
  - Fix a bug with how we walked the resource buffer after _SRS to call
    config_intr() in that the 'end' variable was not properly updated, so we
    could either terminate the loop early or loop after the end of the
    buffer.
