- There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
(bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
since r52045) but even recently added device drivers do this unnecessarily.
Discussed with: jhb, marcel
- While at it, use DEVMETHOD_END.
Discussed with: jhb
- Also while at it, use __FBSDID.

Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.

The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

We don't have a ISA specific shutdown routine at this time, so remove
it. We just moved it to be pci specific, so this was causing compile
problems (linking problems, so I didn't notice since I unwisely just
built the module).

Make sure we set bst and bsh in the softc.

This gets us probing, but not attaching to, ISA cards. More work
needed since the ISA attach routine is return ENXIO right now :-)

Merge in WIP from p4 for supporting ISA pccard bridges conforming to
the ExCA spec, and close cousins:

o Write an activate routine that works.
o merge a couple of items from oldcard before they are lost
o write a deactivate routine

I suspect we're still a ways away from having this work, but maybe for
6.1/5.5?

Use the FreeBSD standard license, since there's no reason to use the
version I have here.

Start each of the license/copyright comments with /*-, minor shuffle of lines

Don't need to declare cbb module. don't know why I never saw
duplicate messages..

Move towards isa attachment for pccbb. This is a work in progress, but
works well with the pci attachment.
