[PATCH 002/142] sh-pfc: Don't define the per-device pinctrl struct instances as global

[Simon Horman]

From: Laurent Pinchart <laurent.pinchart+renesas at ideasonboard.com>

The pinctrl_desc and pinctrl_gpio_range structures registered with the
pinctrl core are per-device instances. Move them to the dynamically
allocated sh_pfc_pinctrl structure and initialize them at runtime.
