this card is based on 16750 UART, modify sio(4) a bit to ignore 16750-specific
7th bit of MCR when probing card. This allows card to be detected and attached
as 16550A-compatible device. More work needs to be done in order to enable
nice 16750-specific features such as larger fifo buffer and higher speeds.

yet that depend on it because sio(4) needs support for it before it
can be used. There's no reason why zs(4) couldn't attach to puc(4)
in the (near?) future (in principle), so don't make memory mapped I/O
support in sio(4) a precondition for this change.
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.
right places, and so it's sorted consistently with how all the other N-hundreds
of files ding this do it.

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.
the structure definitions come from NetBSD to make it easier to share card
definitions. The driver only acts as a shim between the pci bus and the
sio driver. Later pci parallel ports could also be supported through this
driver. Support for most single and multiport pci serial cards should be
as simple as adding its definition to pucdata.c
Tested with the following pci cards:
Moxa Industio CP-114, 4 port RS-232,RS-422/485
Syba Tech Ltd. PCI-4S2P-550-ECP, 4 port RS-232 + 2 parallel ports
Netmos NM9835 PCI-2S-550, 2 port RS-232
