Add the correct hook for devfs to kern_conf.c
The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.
A few drivers had minor additional cleanups performed relating to cdevsw
registration.
A few drivers don't register a cdevsw{} anymore, but only use make_dev().
#define COMPAT_PCI_DRIVER(name,data) DATA_SET(pcidevice_set,data)
.. to 2.2.x and 3.x if people think it's worth it. Driver writers can do
this if it's not defined. (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)
Disable DPARCKEN in the DSCOMMAND0 register on the aic7890/91/96/97.
Parity checking is broken for some chip/MB combinations and this
is the work around recommended by Adaptec.
dpt_pci.c:
Remove a superflous '{' that prevented DPT_ALLOW_MEMIO from working.
pcireg.h:
Add a definition for Parity Error Reponse bit in the PCI Space
command register.
