dt-bindings: pinctrl: ralink: Fix 'enum' lists with duplicate entries

There's no reason to list the same value twice in an 'enum'. This was fixed
treewide in commit c3b0068 ("dt-bindings: Fix 'enum' lists with
duplicate entries"), but this one got added in the merge window.

A meta-schema change will catch future cases.
