aic7xxx_pci.c:
	When performing our register test, be careful
	to avoid resetting the chip when pausing the
	controller.  The test reads the HCNTRL register
	and then writes it back with the PAUSE bit
	explicitly set.  If the last write to the controller
	before our probe is to reset it, the CHIPRST
	bit will still be set, so we must mask it off
	before the PAUSE operation.  On some chip versions,
	we cannot access registers for a few 100us after
	a reset, so this inadvertant reset was causing PCI
	errors to occur on the read to check for paused
	status.
