Remove some more NetBSD compat shims and other unused bits from these
drivers:
- Remove scsi_low_pisa.*, they were unused.
- Remove <compat/netbsd/physio_proc.h> and calls to the stubs in that
header. They were empty nops.
- Retire sl_xname and use device_get_nameunit() and device_printf() with
the underlying device_t instead.
- Remove unused {ct,ncv,nsp,stg}print() functions.
- Remove empty SOFT_INTR_REQUIRED() macro and the unused sl_irq member.

Remove NetBSD compat shims for drivers originally shared with NetBSD/pc98.
NetBSD/pc98 was never merged into the main NetBSD tree and is no longer
developed. Adding locking to these drivers would have made the compat
shims hard to impossible to maintain, so remove the shims to ease
future changes.

These changes were verified by md5. Some additional shims can be removed
that do affect the compiled results that I will probably do in another
round.

Remove OLDCARD support by removing compat shims

Eliminate unused argument in PCMCIA_CARD macro.

Provide a backwards compatible way to have the extra macro by defining
PCCARD_API_LEVEL 5 before including pccarddevs for driver writers that
want/need to have the same driver on 5 and 6 with pccard attachments.

Minor style nits
o remove unneeded {}

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

Fix disordering of pccarddevs.h noticed by bde. Also remove a few
redundant includes and fix some of the include disordering.

Submitted by: bde

Move to generating pccarddevs.h on the fly, both for the kernel and
the modules.

Also generate usbdevs.h automatically now, but a non-kernel file is
stopping that at the moment.

Convert callers to the new bus_alloc_resource_any(9) API.

Move the non-MD machine/dvcfg.h and machine/physio_proc.h to a common
MI area before they proliferate more.

Use __FBSDID().
Also some minor style cleanups.

o Changes to support NEWCARD.
o Add needed headers.
o Add nsp_producs[] product data and nsp_match() function.
o Change nsp_pccard_method[] to support both OLDCARD and NEWCARD.
o Add warning to fall back to PIO mode when it cannot use SMIT mode.
This is needed because memories are not allocated with NEWCARD now.

Remove PAO3 dependent part.
This will not affect either -current nor -stable.

We should not pass the size of the memory to bus_alloc_resource().
We should use 1 to request default iomem.

Catch up with NetBSD/pc98.
o Much cleanly separate NetBSD(XS) / FreeBSD(CAM) codes.
o Improve tagged queing support (full QTAG).
o Improve quirk support.
o Improve parity error retry.
o Impliment wide negotheation.
o Cmd link support.
o Add copyright of CAM part.
o Change for CAM_NEW_TRAN_CODE.
o Work around for buggy KME UJDCD450.

o stg: add disconnet condition.
o nsp: use suspend I/O.

Turn on interrupt-entropy harvesting for all/any mass storage devices
I could find. I have no doubt missed a couple.

Interrupt entropy harvesting is still conditional on the
kern.random.sys.harvest_interrupt sysctl.

o Check the size of I/O window handed by parent bus.
o Check if it is in PIO_MODE when memory window is not handed.

Move nsp_card_intr()'s prototype and definition inside the appropriate
#ifdef's as it is only used in older versions of FreeBSD.

Zap some cut-paste code that isn't used. It #included "apm.h" and
an apm include file but had no other apm references.

select() DKI is now in <sys/selinfo.h>.

Change flags of ncv and nsp driver. Both were conflicted with the flags
used in lower layer (scsi_low.c).

The flag of ncv for KME KXLC004 was chaged from 0x1 to 0x100.
The flag of nsp for PIO mode was chaged from 0x1 to 0x100.

Add PC-Card/ISA SCSI host adpater drivers from NetBSD/pc98
(a NetBSD port for NEC PC-98x1 machines). They are ncv for NCR 53C500,
nsp for Workbit Ninja SCSI-3, and stg for TMC 18C30 and 18C50.

I thank NetBSD/pc98 and bsd-nomads people.
