[PATCH 2/3] pinctrl: single: fix possible memory leak when pinctrl_enable() fails

[Yang Yingliang <yangyingliang@xxxxxxxxxx>]

This driver calls pinctrl_register_and_init() which is not
devm_ managed, it will leads memory leak if pinctrl_enable()
fails. Replace it with devm_pinctrl_register_and_init().

Fixes: 5038a66dad01 ("pinctrl: core: delete incorrect free in pinctrl_enable()")
