i2c-isa: Restore driver owner

Commit 2b48716d back in January
2006 was a bit overzealous. It removed .owner from all i2c drivers,
including i2c-isa ones, while they still need it.

convert drivers/hwmon/*.c semaphore use to mutexes.

the conversion was generated via scripts, and the result was validated
automatically via a script as well.

Now that i2c_add_driver() doesn't need the module owner to be set by
hand, we can delete it from the drivers.  This patch catches all of the
drivers that I found in the current tree (if a driver sets the .owner by
hand, it's not a problem, just not needed.)

We should use the i2c_driver.driver's .name and .owner fields
instead of the i2c_driver's ones.

We could refactor the error message 34 different i2c drivers print if
i2c_detach_client() fails in this function itself. Saves quite a few
lines of code. Documentation is updated to reflect that change.

Note that this patch should be applied after Rudolf Marek's w83792d
patches.

Call the ISA chip drivers detection function directly instead of relying
on i2c_detect. The net effect is that address lists won't be handled
anymore, but they were mostly useless in the ISA case anyway (pc87360,
smsc47m1, smsc47b397 had already dropped them).

We don't need to handle multiple devices, all we may need is a way to
force a given address instead of the original one (some drivers already
do: sis5595, via686a, w83627hf), and, for drivers supporting multiple
chips, a way to force one given kind. All this may be added later on
demand, but I actually don't think there will be much demand.

Convert the 10 ISA hardware monitoring drivers (it87, lm78, pc87360,
sis5595, smsc47b397, smsc47m1, via686a, w83627hf, w83627ehf, w83781d) to
explicitely register with i2c-isa. For hybrid drivers (it87, lm78,
w83781d), we now have two separate instances of i2c_driver, one for the
I2C interface of the chip, and one for ISA interface. In the long run,
the one for ISA will be replaced with a different driver type.

At this point, all drivers are working again, except for missing
dependencies in Kconfig.

The adm9240 driver, in adm9240_detect(), allocates a structure.  The
error path attempts to kfree() ->client field of it (second one),
resulting in an oops (or slab corruption) if the hardware is not present.

->client field in adm1026, adm1031, smsc47b397 and smsc47m1 is the first in
${HWMON}_data structure, but fix them too.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
