Add devicetree bindings for the ADL8113 Low Noise Amplifier.
The bindings include support for specifying gain values of external
amplifiers connected to the two external bypass paths (A and B). These
optional properties allow the gain values to be selectable via the
hardwaregain attribute, enabling complete devicetree description of
the signal chain including external components.

ADRF5740 and HMC540S have a 4 bit parallel interface.
Update ctrl-gpios description and min/maxItems values depending on the
matched compatible to correctly reflect the hardware properties.

Instead of listing directly properties typical for SPI peripherals,
reference the spi-peripheral-props.yaml schema. This allows using all
properties typical for SPI-connected devices, even these which device
bindings author did not tried yet.
Remove the spi-* properties which now come via spi-peripheral-props.yaml
schema, except for the cases when device schema adds some constraints
like maximum frequency.
While changing additionalProperties->unevaluatedProperties, put it in
typical place, just before example DTS.

Another round of wack-a-mole. The json-schema default is additional
unknown properties are allowed, but for DT all properties should be
defined.

Clean-up incorrect indentation, extra spaces, long lines, and missing
EOF newline in schema files. Most of the clean-ups are for list
indentation which should always be 2 spaces more than the preceding
keyword.
Found with yamllint (which I plan to integrate into the checks).
