regulator: max77686: Fix shared GPIOs
This reverts commit c89c00e2b8f0 "regulator: max77686: Pass descriptor instead of GPIO number" as it has problems with shared GPIOs similar to that on s2mps11. Reported-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>
