dt-bindings: pinctrl: rt2880: properly redo bindings

Browse source 
When this bindings where applied there weren't already
reviewed and some old hacks was being used to properly
pass the schemas checks. This commits fix them up:
 - Instead of using 'if-then' clause use '-pins$'.
 - 'groups' and 'function' are included inside a new
   '^(.*-)?pinmux$' node.
 - compatible string is not an 'enum' but a 'const'.
 - 'pinctrl-0' and 'pinctrl-names' removed since they are
    used in consumer nodes.
