pinctrl: samsung: fix suspend/resume functionality
The GPIO states need to be restored after s2r and this is not currently supported in the pinctrl driver. This patch saves the gpio states before suspend and restores them after resume. Saving and restoring is done very early using syscore_ops and must happen before pins are released from their powerdown state. Patch originally from Prathyush K <prathyush.k@samsung.com> but rewritten by Doug Anderson <dianders@chromium.org>.
