SENSORS_LIMIT and the generic clamp_val have the same functionality,
and clamp_val is more efficient.

This patch reduces text size by 9052 bytes and bss size by 11624 bytes
for x86_64 builds.

This patch converts the drivers in drivers/hwmon/* to use the
module_i2c_driver() macro which makes the code smaller and a bit simpler.

As discussed one year ago, the WDIOC_GETSUPPORT ioctl only needs a
mutex because it operates on a static variable. There is no good
reason to keep this variable static, so let's just make it non-static
and drop the now useless mutex altogether.

See the discussion at:

613655fa39ff6957754fa8ceb8559980920eb8ee 02-Jun-2010 Arnd Bergmann <arnd@arndb.de> drivers: autoconvert trivial BKL users to private mutex

All these files use the big kernel lock in a trivial
way to serialize their private file operations,
typically resulting from an earlier semi-automatic
pushdown from VFS.

None of these drivers appears to want to lock against
other code, and they all use the BKL as the top-level
lock in their file operations, meaning that there
is no lock-order inversion problem.

Consequently, we can remove the BKL completely,
replacing it with a per-file mutex in every case.
Using a scripted approach means we can avoid
typos.

These drivers do not seem to be under active
maintainance from my brief investigation. Apologies
to those maintainers that I have missed.
