Instead, we'll take the approach of making a small IIO proximity driver that parses the EC switch bitmap to find out if the front proximity sensor is detecting something or not. This allows us to treat proximity sensors as IIO devices all the time in userspace instead of handling this switch on the EC via the input subsystem and then other proximity sensors via IIO.
