A driver for the DS28E17 1-Wire to I2C bridge chip.

This chip acts like a 1-Wire slave device and provides a iic(4) master
at the end of the 1-Wire bus. More or less it is the polar opposite
of the DS2482 [ds2482ow(4)] chip.

This device couples well with ds2482ow(4) and can be used to provide a
I2C bus at very great lengths from the controlling computer.

All features of the chip are supported, except for 1-Wire overdrive
support, which requires more work from the onewire(4) infrastructure.

The chip does not support Read without Stop. Attempts to do this will
get turned into a Read with Stop and one will have to hope for the
best. The chip also does not support zero length I2C reads or zero
length I2C writes. This has the side effect of making the default
mode, a zero length I2C write, for i2scan(8) return false positives.
The alternative mode that i2cscan(8) can use, the single byte read,
should work as expected.

The chip has automatic support for end devices that do I2C clock
stretching.

It was noticed that this chip does not work with the gpioow(4) driver.
That might be an interesting thing to debug if one has a good logic
analyzer on hand. While the presence pulse is detected, the gpioow(4)
driver is not able to complete the initial ROM enumeration. The
DS28E17 works flawlessly when driven by a DS2482 [ds2482ow(4)] driver
chip. Poke me if you want any more details.

The chip is pretty inexpensive and only requires a single cap to get
it hooked up. However, the package it comes in is only a 16-QFN
package, so it could provide to be hard to solider onto a board for
some. There are side tabs, so it was possible with a very small iron
and lots of flux. There is a slightly expensive breakout board sold
by Mikroe that probably works well -> https://www.mikroe.com/1-wire-i2c-click

Add ncm(4) a driver for USB Network Control Model

Add a driver for the Maxim DS2482-100 and DS2482-800 I2C to 1-Wire
bridge.

This chip provides a I2C device that then has 1 or 8 1-Wire busses on
the other side. The 1-Wire buses show up as onewire(4) buses in the
NetBSD.

The chip can be used in situations where:

* You have a I2C bus extended a long distance, say with a LTC4311
active terminator / extender or one of the differential I2C
extenders and you would like to have a 1-Wire device on the far end
and it isn't possible to add wiring to get to the far end.

* You are either out of GPIO pins or the GPIO pins are not reliable
enough to use gpioow(4), but you do have working I2C.

The DS2482 does all of the 1-Wire signals in hardware and provides for
a couple of pullup options for the 1-Wire devices.

All of the functions of the DS2482-100 and -800 are supported except
for overdrive speed support. To do this will likely require some API
changes to onewire(4).

Breakout boards exist for the DS2482 for both variants, but they
appear to be more expensive than expected. The chip itself is quiet
cheap and wasn't all that hard to SMD solder to a board. No other
components are really needed.

There are other members in the same family, the DS2482-101, DS2484 and
DS2485. The DS2482-101 has a sleep pin, but from the datasheet
appears to program the same as the -100 variant. The DS2484 has a
slightly different way to set configuration information and probably
won't quite work with the driver, but isn't far off. The DS2485 is
very different and would require a new driver to function.

On this architecture vmt(4) used to search for a node "/hypervisor" in the
FDT and probed the VMware hypervisor call only when the node was
found. However, things appear to have changed and VMware no longer provides
the FDT node.

Since vmt(4) doesn't actually need to read anything from FDT, and the
hypervisor call logically resides in virtual CPUs themselves, it would be
better to attach it directly to cpu, just like how it's probed on x86.

This driver is not built-in by default, thus loadable module can help (un)lucky
owners of 64-bit capable VIA (Nano/Eden) systems or early AMD/Intel systems
with some VIA chipsets, which include VIA integrated graphics.
I also boldly added product IDs for few later models from VX8xx/VX9xx chipsets
without 3D support (DX9_0) to "expand" the driver support to more systems.
Tested successfully basic functionality on VX800, and partially successfully
on VX900 (on VX900 Xorg failed to initialize due to openchrome related issues,
viadrmums attaches and it is by used the driver).
Didn't test on VX855, I don't have one.
