When illuminance0_calibbias gets 4000 (for a 4x multiplier), we see lux
granularity of 4. Reversing the order of the right shift and multiplication
retains the precision of the unadjusted lux value.

Fix a dumb lack of consideration of the effect of combining
the iio_device_unregister and iio_free_device calls into
one. There is no valid place to free some of the sysfs
array elements.

Lots of people expect module.h to just "be there" without
any #include effort. But we are crushing that. So fix those
files in staging relying on implicit module.h presence.

There are some unusual corners in the probe function of this
driver, so may need another look.
V2: Now with the check for allocation success not inverted.
V3: Now with the i2c devdata calls actually being correctly cast.

Getting rid of messages that make it harder to spot important issues.
Some code removed that will be useful one day. Can put it back then.

This was suggested by Arnd Bergmann, Other elements may well
move in here in future, but it definitely makes sense for these.

Suggested by Arnd Bergmann. Note this will break ALL drivers that
are out of mainline. The fix is trivial change of
iio_allocate_device() -> iio_allocate_device(0)
Sorry if this causes issues for any one!
V2: Include new drivers in the update

Added suspend/resume functions.
Changed attribute names to match existing where applicable and updated
or documented new ABI as discussed.
Changed integration time ABI from using index (0 to 3) to use actual
gain values (1x,8x, etc.).
Removed various unused variables, declarations, and functions.
Revised code to accommodate different endianess (le16_to_cpu).
Updated error return codes in various functions.
Changed from mdelay to msleep after determining that longer wait would
be acceptable.
V5: Makefile and Kconfig cleanups by Jonathan Cameron.
