bridge in the device tree which lacks the mandatory (also by the OFW PCI
bus binding spec) "reg" property. Change the code to just ignore nodes
missing the "reg" property instead of panicing when encountering such a
node. Also ignore nodes without a "name" property (guaranteed by the OFW
PCI bus binding spec). This brings the behaviour of the MD OFW PCI code
regarding such incomplete nodes in line with the EBus and the SBus code.

o rework pll setup code to follow h/w specification
o add hint.hifn.X.pllconfig to specify reference clock setup
requirements; default is pci66 which means the clock is
derived from the PCI bus clock and the card resides in a
66MHz slot
Tested on 7955 and 7956 cards; support for 7954 cards not enabled
since we have no cards to test against.

Rather than have a twisty maze of special case allocations, move
instead to a data driven allocation. This should be the most robust
way to cope with the resource problems that the multiplicity of ways
of encoding 5 registers that have the misfortune of not being a power
of 2 nor contiguous.
Also, make it less impossible that pccard will work. I've not been able
to get my libretto floppy working, but it now fails later than before.
phk and I had similar ideas on this during the 5.3 release cycle, but
it wasn't until recently that I could test more than one allocation
scenario.

upper bits of the 64 bit division. We only had a 50% chance of scaling up
the blocksize for large NFS client mounts when it was needed. For 5.x and
beyond, this was harmless because we could represent the result in either
case. For 4.x this was a big problem though. (4.x also has a df(1) bug to
compound the problem)

support the producer/consumer attribute.
Hold a lock on the table instead of futzing with reference counts which
was potentially dangerous except drivers were quiescent while we did this
so the table contents never changed. Disable the hack logic for removing
scan candidates with multiple association failures; it's never done the
right thing and will be fixed correctly with background scanning goes in.

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.
