iio: light: cm32181: Add some extra register defines
These come from a newer version of cm32181.c, which is floating around
the net, with a copyright of:
* Copyright (C) 2014 Capella Microsystems Inc.
* Author: Kevin Tsai <ktsai@capellamicro.com>
*
* This program is free software; you can redistribute it and/or modify it
* under the terms of the GNU General Public License version 2, as published

Note that this removes the bogus CM32181_CMD_ALS_ENABLE define, there
is no enable bit, only a disable bit and enabled is the absence of
being disabled.
This is a preparation patch for adding support for the older
CM3218 model of the light sensor.
