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

Add also gpio-reserved-ranges with min/maxItems (see for example sm8450)
and gpio-line-names with maxItems.

Contents of this enum is sorted usually by name (not always, but we try
for new bindings)

No underscores in node names.. which points to next one:

Does not look like you tested the bindings. Please run `make
dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
