Subject: [PATCH v2 2/3] dt-bindings: gnss: u-blox: add "reset-gpios" binding

Needed to enable this chip on a Renesas KingFisher board. Description
copied over from the Mediatek driver which already supports it.

Changes since v1:
* dropped obvious description (Thanks, Geert!)
* added missing include (Thanks, Krzysztof and Rob!)

I build tested the change this time.
