thorpej 8068d9eeb2 Handle cases like the following: 
- controller calls scsi_done() with error XS_TIMEOUT
	- scsi_done() calls sddone()
	- sddone() calls disk_unbusy()
	- scsi_done() calls controller to retry command (missing the
	  call to disk_busy())
	- controller calls scsi_done()
	- scsi_done() calls sddone()
	- sddone() calls disk_busy(), which panics because of the imbalance.
Bug noticed by Leo Weppleman, who also suggested this fix; pass an additional
boolean argument ("complete") to the device's "done" routine, with a
value of `0' passed from the previous call to "done", and add an additional
call to "done" when the xfer resources are freed.

chuck b5ddd8431d dmamatch never added in the offset for the dma registers to the VA, 
and thus probed the wrong address on the 4/300 (but it worked because
it was probing the esp0 registers!).

now that bus_tmp() adds the offset in for us [as of obio 1.19] i
discoved that a byte access to the dma registers is not allowed.
so, i've change probeget to use a word access.

chuck afb262e8da improved handling of mapping of devices who's registers do not reside on 
page boundaries:
 - change bus_tmp() to include the offset from the start of page in the
        returned KVA [rather than forcing each driver to add it back in
        individually]
 - changed bus_map() to include the offset from the start of page in the
        the returned value if a mapping is found in the PROM's KVA area
 - clarified a few comments

chuck c488310462 change mapdev() so that it includes the offset from the start of the 
page in the virtual address it returns.

in sys/dev/tc.

jonathan 28cf41d710 Change the order of members of struct confargs, to be closer to 
the sys/dev/tcvar.h TurboChannel configuration structures. (the initializers
in sys/arch/pmax/tc were already changed; the structure definition wasn't,
which broke autoconfiguration.)

thorpej 524cf97f54 Kludge around a case where a flaky HP-IB disk might be slow to respond 
to the identification request in rdmatch().  Similar in spirit to a
patch from Jason Downs (written eons ago), but limited to the broken
device we're trying to reach.  My patch tested (and fixed :-) by
Herb Peyerl.
