IIO fixes for v3.6-rc1
These mostly consist of fixes from Lars-Peter Clausen that were
the first part of a large series reworking the drivers concerned.
Turns out these drivers had quite a wealth of minor bugs.
Also here are some build warning fixes for lm3533-als and
adjd_s111 (both new drives in this cycle).
Final elements are a a div factor overflow and a warning
related fix in a couple of Analog Devices drivers.
All in all nothing major, but a worthwhile bunch of short
fixes.
The values reported by the AD7780 are unsigned with a binary offset:
0x000000 is negative fullscale
0x800000 is zeroscale
0xffffff is positive fullscale
So mark the channel in the channel spec as unsigned rather than signed.

The temperature channel reports values in degree Kelvin with sensitivity of 5630
codes per degree. If the chip is configured in bipolar mode there is an
additional binary offset of 0x800000 and the sensitivity is divided by two.
Currently the driver does the mapping from the raw value to degree Celsius when
doing a manual conversion. This has several disadvantages, the major one being
that it does not work for buffered mode, also by doing the division by the
sensitivity in the driver the precession of the reported value is needlessly
reduced.
Furthermore the current calculation only works in bipolar mode and the current
scale is of by a factor of 1000.
This patch modifies the driver to report correct offset and scale values in
both unipolar and bipolar mode and to report the raw temperature value
for manual conversions.

In bipolar mode there is a a binary offset of 2**(N-1) (with N being the number
of bits) on the reported value. Currently this value is subtracted when doing a
manual read. While this works for manual channel readings it does not work for
buffered mode. So report the offset in the channels offset property, which will
work in both modes.

The values reported by the AD7793 are unsigned.
In uniploar mode:
0x000000 is zeroscale
0xffffff is fullscale
In bipolar mode:
0x000000 is negative fullscale
0x800000 is zeroscale
0xffffff is positive fullscale
In bipolar mode there is a binary offset, but the values are still unsigned.

The temperature channel uses the internal 1.17V reference with 0.81 mv/C. The
reported temperature is in Kevlin, so we need to add the Kelvin to Celcius
offset when reporting the offset for the temperature channel.

Commit 3902a37028 (staging: comedi:
refactor comedi_device_attach() a bit) by yours truly introduced an
inverted logic bug in comedi_device_attach() for the case where the
driver expects the device to be configured by driver name rather than
board name. The result of a strcmp() is being tested incorrectly. Fix
it.
Thanks to Stephen N Chivers for discovering the bug and suggesting the
fix.

As mentioned by Ian Abbott, the pci address passed to ioremap
should be a resource_size_t not an unsigned long. Use a local
variable of that type to hold the pci_resource_start() that is
passed to ioremp().
Set the dev->iobase to a dummy non-zero value so that the "detach"
can use it as a flag to know that comedi_pci_disable() needs to
be called.
