regulator: fixed/gpio: Revert GPIO descriptor changes due to platform breakage Commit6059577cb2"regulator: fixed: Convert to use GPIO descriptor only" broke at least the ams-delta platform since the lookup tables added to the board files use the function name "enable" while the driver uses NULL causing the regulator to not acquire and control the enable GPIOs. Revert that and a couple of other commits that are caught up with it to fix the issue:2b6c00c157"ARM: pxa, regulator: fix building ezx e680"6059577cb2"regulator: fixed: Convert to use GPIO descriptor only"37bed97f00"regulator: gpio: Get enable GPIO using GPIO descriptor" Reported-by: Janusz Krzysztofik <jmkrzyszt@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
