Some updates and bug squashing in the firewire stack.

Move the interupt handler to a driver_intr_t type function as it was trying
to do way to much for a lightweight filter interrupt function.

Introduce much more locking around fc->mtx. Tested this for lock reversals
and other such lockups. Locking seems to be working better, but there
is much more to do with regard to locking. The most significant lock is
in the BUS RESET handler. It was possible, before this checkin, to set
a bus reset via "fwcontrol -r" and have the BUS RESET handler fire before
the code responsible for asserting BUS RESET was complete. This locking
fixes that issue.

Move some of the memory allocations in the fc struct to the attach function
in firewire.c

Rework the businfo.generation indicator to be merely a on/off bit now.
It's purpose according to spec is to notify the bus that the config ROM
has changed. That's it.

Catch and squash a possible panic in SBP where in the SBP_LOCK was held
during a possible error case. The error handling code would definitely
panic as it would try to acquire the SBP_LOCK on entrance.

Catch and squash a camcontrol/device lockup when firewire drives go away.
When a firewire device was powered off or disconnected from the firewire
bus, a "camcontrol rescan all" would hang trying to poll removed devices
as they were not properly detached. Don't do that.

Change the remainder of the drivers for DMA'ing devices enabled in the
sparc64 GENERIC and the sound device drivers known working on sparc64
to use bus_get_dma_tag() to obtain the parent DMA tag so we can get rid
of the sparc64_root_dma_tag kludge eventually. Except for ath(4), sk(4),
stge(4) and ti(4) these changes are runtime tested (unless I booted up
the wrong kernels again...).

The Sony i.LINK CXD1947 device is a firewire bridge, but it doesn't
implement the OHCI programming interface. Thus it probes, but fails
to attach because of an invalid OHCI version. Rather than count on
the downstream tests properly failing, print a message that this
chipset isn't supported and fail the probe.

Recognize the integrated (though not necessarily enabled) FireWire
controllers of Sun PCIO-2 chips which are used onboard in most of
the newer PCI-based sun4u machines (cosmetic change as they were also
already probed as generic FWOHCI without this). As with gem(4), hme(4)
and ohci(4) detect whether their intpin register is valid and correct
it if necessary, i.e. set the respective IVAR to the right value for
allocating the IRQ resource, as some of them come up having it set
to 0 (in fact in all machines I'm currently aware of the FireWire
part being enabled). This fixes attaching affected controllers.

Add some PCI IDs for OHCI chips.

Trim a few things from the dmesg output and stick them under bootverbose to
cut down on the clutter including PCI interrupt routing, MTRR, pcibios,
etc.

Discussed with: USENIX Cabal

Remove the setting of the pci config variables on power state changes.
The bus does this now.

Change u_intXX_t to uintXX_t. Change a couple of 'unsigned long's to
uint32_t where appropriate.
