Fxi a bunch of typos.

PR: misc/174625
Submitted by: Jeremy Chadwick <jdc@koitsu.org>

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.

Prefer new location of pci include files (which have only been in the

Make sure that pp_name is non-null before setting the device

necessary...

Remove even more Copy&Pasted sets of #includes.

Quick, low impact band-aide to unbreak the build. Added && 0 so we

o Busy loop did not timeout. Change this to timeout as original NetBSD/pc98.
