Document the legacy Lantiq device tree bindings.
Compatible strings for xRX100 (ar9) and newer SoCs
should be renamed and will be added later.

This suggests you are documenting existing compatibles, but I do not see
them at all. Confusing.

Please wrap commit message according to Linux coding style / submission
process (neither too early nor over the limit):
https://elixir.bootlin.com/linux/v5.18-rc4/source/Documentation/process/submitting-patches.rst#L586

Subject: drop second/last, redundant "dt bindings". The "dt-bindings"
prefix is already stating that these are bindings.

This does not look like proper board compatible. Boards have almost
always minimum two compatibles - one for SoC and one for board. With
commit msg this just adds to confusion...

The added compatible strings can be found in:
- arch/mips/lantiq/xway/sysctrl.c,
- arch/mips/lantiq/falcon/prom.c,
- arch/mips/lantiq/xway/prom.c.
Upstream only has one dts for danube development board. More dts
can be found in OpenWRT [1]. I have a bunch of these devices and
intend to send dts files upstream.

Will be fixed in v2.

The added dt-binding contains only the SoC part. The compatible strings
for individual boards will be added later together with the dts files. Before
sending the dts files I want to document current bindings and clear
checkpach warnings about undocumented strings.

Which is incomplete and inaccurate documentation. Instead, document
proper, full compatibles.
