[PATCH v1 1/1] pinctrl: cherryview: Return correct value if pin in push-pull mode

Currently the getter returns ENOTSUPP on pin configured in
the push-pull mode. Fix this by adding the missed switch case.

Fixes: ccdf81d08dbe ("pinctrl: cherryview: add option to set open-drain pin config")
Fixes: 6e08d6bbebeb ("pinctrl: Add Intel Cherryview/Braswell pin controller support")
