dk(4): Add support for discovering Atari TOS partitions as wedges

Any partitioning scheme which conforms to the Atari AHDI 3.00 spec should be
recognized by the new DKWEDGE_METHOD_TOS.

fix spelling mistakes, mainly in comments and log messages.

Re-factor the Goldfish RTC driver into attach-front-end and generic
back-end; Goldfish virtual devices can be found on virtual platforms
that don't use FDT.

Rework AHCISATA_EXTRA_DELAY for kern/56737

Rework AHCISATA_EXTRA_DELAY for kern/56737

- Remove AHCI_QUIRK_EXTRA_DELAY as issue appears to be drive and
not controller related
- Replace AHCISATA_EXTRA_DELAY with AHCISATA_REMOVE_EXTRA_DELAY,
so defaulting to enabling the extra delay, as the downside of
slower probing on systems which do not need it is less than having
other systems intermittently fail to probe and attach drives
- Also allow disabling extra delay with AHCISATA_EXTRA_DELAY_MS = 0

We should return to this code to work out which of the extra delays
are needed, and how long they need to be. It may be that faster
systems are more likely to trigger the issue (I've only seen it on
a 13th gen i7-13700, though only tested on a limited set)

config(5): enable NTP option implicitly when PPS_SYNC option is enabled.

PPS_SYNC requires NTP, but some code blocks are ifdef'ed without it,

config(5): enable NTP option implicitly when PPS_SYNC option is enabled.

PPS_SYNC requires NTP, but some code blocks are ifdef'ed without it,
thus allowing an attempt to build kernel with PPS_SYNC, and without NTP
(and it almost builds with one line change).

Update options(4) man page to reflect the change.

Solution suggested by riastradh.

sys: Include files.acpica unconditionally.

This way acpica.h always exists unconditionally, so MI code can be
conditional on NACPICA.

It is not great to have such conditionals, but it's better to have

#include "acpica.h"

#ifdef NACPICA > 0

than to have

#if defined(__i386__) || defined(__x86_64__) || defined(__arm__)
#include "acpica.h"
#endif

#ifdef NACPICA > 0

and we can still grep for NACPICA to find places that could be
factored better.

Re-factor and overhaul the "mcp23s17gpio" driver as "mcpgpio", and
add support for 8-bit and I2C variants of the chip:
- MCP23008 / MCP23S08: 8-bit (I2C / SPI)
- MCP23017 / MCP23S17: 16-bit (I2C / SP

- MCP23008 / MCP23S08: 8-bit (I2C / SPI)
- MCP23017 / MCP23S17: 16-bit (I2C / SPI)
- MCP23018 / MCP23S18: 16-bit (I2C / SPI), open-drain outputs

The MCP23x17 and MCP23x18 are essentially identical, software-wise; we
merely report different GPIO pin capabilities (no push-pull output for
MCP23x18). Also, remove the tri-state capability that was previously
advertised by the old version of this driver; these chips have no way
to put the pin into a HI-Z mode.

All 3 I2C versions are supported, but the SPI front-end still only
supports the MCP23S17 for now (SPI autoconfiguration needs an overhaul).

mcp23s17gpio(4) remains present as a link to the new mcpgpio(4) man page.

XXX Still to-do: FDT integration, interrupt suppoort.

A driver and user land utility for the Sparkfun Serial Controlled Motor
Driver module as illustrated here:

https://www.sparkfun.com/products/13911

A SCMD module is a ARM SOC simular to a Arduino in front of a motor
driver chip. The single SCMD module can control two motors and up to
16 additional modules can be chained together using an internal I2C
bus. One can interface with the SCMD using tty uart commands, SPI or
I2C. The driver in this commit adds a kernel driver for the I2C and
SPI interfaces. The command line utility provides a set of
convenience commands that support most of the functions of the SCMD
and is able to use the tty uart mode, SPI user land or the included
kernel driver in a uniform manor.

The use of the SCMD module is mostly for small robots and the like,
but it can control anything that is controllable by voltage.

ahcisata(4): Introduce AHCI_QUIRK_EXTRA_DELAY quirk for devices that
need extra delays as done by AHCISATA_EXTRA_DELAY option.

Enable this quirk for "C600/X79 AHCI". Also add commented out quirk
entries for "Bay Trail SATA (AHCI)" and "Mobile AHCI SATA Controller",
for which non-reproducible failures worked around by extra delays have
been reported.

500 ms of delays inserted by these option/quirk may be too much. Add
AHCISATA_EXTRA_DELAY_MS option to adjust number of delays in ms, like:

----
options AHCISATA_EXTRA_DELAY_MS=200
----
