These two changes make kldload of a pccard driver work again.

with the on-board interface on the IBM x235 server.

- Get the initial mode from the prom settings and don't clobber the mode
on open.
- Copy output into an internal ring buffer instead of accessing the tty
outq directly in the interrupt handler. This fixes a problem where
garbage would show up in the output stream.
- Reset the console port completely and reprogram all the parameters
before enabling it. This fixes seemingly random hangs on startup
when using a fast interrupt handler.
- Add minimal locking in place of spls.
- Remove dead code and minor cleanups.
any machine dependent initialization. This allows the MD code to set the
interrupt routing model so that PCI interrupts are routed correctly when
using an APIC or SAPIC for example.
In this installment, we learn that it is bad to access registers that
are only defined for mfc cards in the interrupt handler when we do not
in fact have a mfc card. For MFC cards, we'll only call the ISR if
the this card interrupted bit is set. For non mfc cards (which are
basically 90% of pccards in use), we always call the ISR and avoid
touching the suspect registers. We always pacify the bit in the MFC
case on the off chance that will help in the itnerrupt handler not
being registed.
when the first PCI bus attaches.
- Create /dev/pci during MOD_LOAD as well.
- Destroy /dev/pci during MOD_UNLOAD (not that you can kldunload pci, but
might as well get the code right)
PUC devices live on pccard or pci so INTR_FAST is never really an option.
Don't try to register the interrupt as fast and don't allow the children
to do so either.
- add bus capabilities into the driver, so that it is possible for a radio
driver to attach to it to use shared resources of fm801 chip. The radio
driver itself will be committed later.

a) we don't believe what the board tells us all the time (if the BIOS
hasn't run, port page 2 and port page 0 tend to be garbage)
b) add the missing code to set parameters for the SPI cards.

Don't expect all RIDs to be PCI rids. The previous code made at
least 1 mistake, even for PCI.
Give the card definitions a chance to specify a init function.
Use this instead of the gross superio hack.
Move the win877 init function to puc_pci.c where it belongs.
RIDs can actually be zero, don't set badmuxed if so.
Set a less incorrect end for the construct SYS_RES_IOPORT entries,
I guess both sio and lpt happen to use 8 IO ports, but that shouldn't
really be hardcoded this way.
Fixup puc_pccard.c to match.
We're getting closer.
Don't set the CCR_OPTION register when registering/deregistering
interrupts unless the card is a MFC card. This makes a lot of cards
work that didn't work before. These bits are only defined for MFC
cards.
Remove COOKIE_FOR_WARNER kludges that phk introduced.
Add more debug info.
Annoy the purists by committing two minor style nits at the same time.
Many thanks to phk. He tracked this problem down to what was screwing
things up, so fixing it became trivially easy once the problem was
understood.
This ensures that we don't enter our interrupt handler until
all OSM components it might reference have been fully initialized
during attach.
Remove vestiges of untagged queue handling.
Add hints to ahd_get_scb() so it knows what type of SCB collision
management to perform for each new transaction.
Properly disable/enable IU_REQ with changes in tagged queuing and
disconnection settings passed in by CAM.
