[ALSA] aoa: platform function gpio: ignore errors from functions that don't exist
Sometimes we simply want to turn off or on everything, and when recently a warning was added when a certain platform function can't be called, this triggered all the time in those cases. This patch shows the warning only if the error was different from the function not existing. The alternative would be to not even try calling the function when it doesn't exist by first checking which exist and then only calling those that do, but that adds complexity that isn't necessary.
