Will Andrews 9129104227 Fix remote DMA based firewire debugging when targeting
systems with more than 4GB of physical memory.

To remotely debug the system 'stealthy' which has a kernel
with this change installed and firewire properly configured:

	% fwcontrol -m stealthy (or stealthy's firewire EUI64)
	% kgdb kernel /dev/fwmem0.0

sys/dev/firewire/fwohci.c:
	Rather than hard code the upper limit for hw based
	automatic responses to remote DMA requests at 4GB,
	program the hardware using Maxmem, the page number
	one higher than the highest physical page detected
	in the system.

	While here, garbage collect more useless splfw()
	calls.
