Add initial device tree for the BeagleV Starlight Beta board. About 300
of these boards were sent out as part of a now cancelled BeagleBoard.org
project.

I2C timing data is based on the device tree in the vendor u-boot port.

On the StarFive JH7100 SoC the uart core clocks can't be set to exactly
16 * 115200Hz and many other common bitrates. Trying this will only
result in a higher input clock, but low enough that the uart's internal
divisor can't come close enough to the baud rate target. So rather than
try to set the input clock it's better to rely solely on the uart's
internal divisor.

Add a combined pinctrl and gpio driver for the StarFive JH7100 SoC.

For each "GPIO" there are two registers for configuring the output and
output enable signals which may come from other peripherals. Among these
are two special signals that are constant 0 and constant 1 respectively.
Controlling the GPIOs from software is done by choosing one of these
signals. In other words the same registers are used for both pinmuxing
and controlling the GPIOs, which makes it easier to combine the pinctrl
and gpio driver in one.

I wrote the pinconf and pinmux parts, but the gpio part of the code is
based on the gpio driver in the vendor tree written by Huan Feng with
cleanups and fixes by Drew and me.

The empty memory nodes, where no memory resides in, are allowed.
The NUMA node IDs are still valid and parsed, but memory may be
added to them through hotplug afterwards. Currently, QEMU fails
to boot when multiple empty memory nodes are specified. It's
caused by device-tree population failure and duplicated memory
node names.

The device-tree specification doesn't provide how empty NUMA
nodes are handled. Besides, I finds difficulty to get where
this case is documented. So lets add a section for empty memory
nodes to cover it in NUMA binding document.

Drop another redundant maxItems that snuck into w1-gpio binding.

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.
