Subject: [PATCH] dt-bindings: gpio: mpfs-gpio: Add pic64gx GPIO compatibility

From: Pierre-Henry Moussay <pierre-henry.moussay@...rochip.com>

pic64gx GPIO is compatible with mpfs-gpio controller, add it with a
fallback.

The diff here is kinda scuffed, because for some reason this binding had
an "items: - enum" construct to begin with.
