pinctrl: single: fix possible memory leak when pinctrl_enable() fails

Browse source

[ Upstream commit 8f773bfbdd ]

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().
And call pcs_free_resources() if pinctrl_enable() fails.
