missing and drop any duplicate properties.

dt-bindings: leds: intel,lgm: Add missing 'led-gpios' property

The example has 'led-gpio' properties, but that's not documented. As the
'gpio' form is deprecated, add 'led-gpios' to the schema and update the
example.

dt-bindings: Clean-up undocumented compatible strings

Adding checks for undocumented compatible strings reveals a bunch of
warnings in the DT binding examples. Fix the cases which are typos, just
a mismatch between the schema and the example, or aren't documented at all.
In a couple of cases, fixing the compatible revealed some schema errors
which are fixed.

There's a bunch of others remaining after this which have bindings, but
those aren't converted to schema yet.
