Subject: [PATCH 3/8] pinctrl: move the U300 GPIO driver to pinctrl

From: Linus Walleij <linus.walleij@...aro.org>

This driver will be converted to a dual GPIO + pinctrl driver
since it supports biasing and driving control options. Hopefully
it can serve as an example.

Signed-off-by: Linus Walleij <linus.walleij@...aro.org>
