These are hardware configuration options which are required in
the linux/openwrt device trees for the IPQ4018/IPQ4019 devices.
Since this isn't obtained from linux upstream but instead from
openwrt, this can't go in contrib; instead it is going in
sys/dts/include/ .

The old vendor tree was never fully merged and doing partial merge isn't
supported with git subtree merge so a new one was created.
Switch the build to use the new DTS from sys/contrib/device-tree
This also bump the DTS used to be in sync with Linux 5.9
While here change the way to get the linux version, simply hardcode
the value in sys/dts/freebsd-compatible.dts and use awk to get that
to put it in the CFLAGS.
As a bonus we now have the bindings docs available
in sys/contrib/device-tree/Bindings/ so no need to link to the Linux repo
or to the vendor tree.

There were two main problems here:
1.) sys/dts/Makefile.inc is not included from various */overlays directories
by default, only ../Makefile.inc
2.) When shelling out for DTS/DTSO, cwd != .CURDIR, so enumeration always
failed
These changes allow make test-dts and make test-dtso to function in their

(e.g. RocketChip, lowRISC and derivatives).
RISC-V page table entries support A (accessed) and D (dirty) bits. The
spec makes hardware support for these bits optional. Implementations that
do not manage these bits in hardware raise page faults for accesses to a
valid page without A set and writes to a writable page without D set.
Check for these types of faults when handling a page fault and fixup the
PTE without calling vm_fault if they occur.

property for spi devices, although in the spigen case it's expected that
the speed will be overridden at runtime via the ioctl interface. A very
conservative 500khz speed is used (I've never seen a spi device that
couldn't run at 1mhz).
By adding spigen-rpi{2,-b}.dtso to fdt_overlays= in loader.conf, the fdt data
will set up the correct pinmux and device nodes to create a spigen(4) device
for each available chipselect pin.

The 4.16 DTS import brought in emac support for the a83t. Since these
boards' DTS is pulled from /boot and I forgot to hook these up to the build,
they should be fairly safe to go away.
The a83t-sid and h3-sid overlays are still relevant. a83t-sid will likely
come in with 4.18 DTS.
This patch implements and exports functions described
in gpio_if.m file. It also uses new gpiobus_attach_bus function
instead of adding gpioc and gpiobus as children. It removes
ulgy reading SoC ID and related if..else, so it depends only on
data read from FDT.

On Raspberry Pi platform GPIO controller also responsible for pins
multiplexing. Pi code predates proper FDT support in FreeBSD so a
lot of pinmux info is hardcoded. This patch:
- Implements pinctl methods in bcm2835_gpio
- Converts all devices with ad-hoc pinmux info to proper pin control
mechanisms and adds pinmux info in FreeBSD's custom dts files.
- Adds fdt_pinctrl option to RPI2 and RPI-B kernels
- Adds SPI pinmux config to FreeBSD's customization of GNU DTS.

The sun8i-a83t-bananapi-m3-emac overlay technically doesn't match what will
be coming from upstream. The tx-delay and rx-delay should be specified in
terms of allwinner,tx-delay-ps and allwinner,rx-delay-ps respectively. The
