Summary:
Newer OPAL device trees, such as those on POWER9 systems, use 'pciex' for
device_type, not 'pci'. Rather than enumerating all possible variants, just
check for a 'pci' prefix.

The driver assumes the list can change (even though it does't right now)
and queries it every time the sysctl runs.
sysctl dev.<nexus>.<inst>.local_cpus

These are represented as booleans on the kernel-side, but were being exposed
as int. This was causing some funky things to happen when read later with
sysctl(8), e.g. randomly reading super-high when the value was actually

This was the wrong solution to the problem; regulator_shutdown invokes
regnode_stop. regulator_stop is not a refcounting method, but it invokes
regnode_enable, which is.
mmel@ has a proposed patch/solution to instead provide regnode_fixed_stop
behavior that properly takes shared GPIO pins into account.

regnode::enable_cnt is generally used to refcount regulator nodes. For
GPIOs, the refcount was done on the gpio_entry since more than one regulator
can share a GPIO.
GPIO regulators were not taking part in the node refcount, since they had
their own mechanism. This caused some fallout after manu started disabling
everybody's unused regulators in r331989.

Differences between LAN7800 and LAN7850 from the driver's perspective:
* The LAN7800 muxes EEPROM signals with LEDs, so LED mode needs to be
disabled when reading/writing EEPROM. The EEPROM is not muxed on the
LAN7850.
* The Linux driver enables automatic duplex and speed detection when
there is no EEPROM, for the LAN7800 only. With this FreeBSD driver
LAN7850-based adapters without a configuration EEPROM fail to link
(with or without the automatic duplex and speed detection code), so
I have just followed the example of the Linux driver for now.

with the following -Werror warnings:
cc1: warnings being treated as errors
/usr/src/sys/dev/drm2/i915/intel_display.c:8884: warning:
initialization from incompatible pointer type
This is due to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=36432, which
incorrectly interprets the [] as a flexible array member.
Because base gcc does not have a -W flag to suppress this particular
warning, it requires a rather ugly cast. To not influence any other
compiler, put it in a #if/#endif block.

If we fail noise floor calibration then we may end up with a deaf NIC
which we can't recover without a full chip reset.
Earlier chips seem to get less stuck in this condition versus AR9280/later
and AR9300/later, but whilst here just fix up the AR5212 era chips to also
return NF calibration failures.
This HAL routine would only return failure if the channel was not configured.
This is a no-op until the driver side code for doing resets and the HAL
code for being told about the reset type (and then handling it!) is
implemented.
Tested:
* AR9280, STA mode
* AR2425, STA mode
* AR9380, STA mode
