regulator: sy7636a: Store the epd-pwr-good GPIO locally
Instead of storing the GPIO state in the mfd (where it isn't used) store it in the regulator. Signed-off-by: Alistair Francis <alistair@alistair23.me> Link: https://lore.kernel.org/r/20210803084456.198-7-alistair@alistair23.me Signed-off-by: Mark Brown <broonie@kernel.org>
