Syntax fix in fwohci_pci_suspend().

- Replace printf() with device_printf().
- Separate fc->dev (i.e. fwohci0) and fc->bdev (i.e. firewire0).
- Remove unused firewirebusreg.h.
- Reduce size of descriptor block for asynchronous transmit and
check the number of descriptor when copying from mbuf.
- Skip mbuf whose length is zero. NFS seems passing such mbuf and
some chips generates unrecoverable error.

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...).
