Fifth round of IIO new drivers, cleanups and functionality for the 3.13 cycle.

New Driver
* Freescale mag3110 magnetometer driver.

New functionality
* Add LPS001WP support to the ST pressure driver.
* Allow the max1363 driver to use only smbus functions for 8 bit devices. This
  allows the driver to be used when more extensive i2c support is not
  available.

Cleanups
* Fix incorrect description of unit conversions in ak8975.
* Switch to pr_err in industrialio-core.c instead of direct printk calls.
* Some simple redundant error handling removal patches.
* Trivial warning suppression by adding brackets to a sizeof call.
* Drop redundant of_match_ptr casts in drivers that are dependent on
  OF supporting being present.  The only purpose of the of_match_ptr
  wrapper was to make stubbing out of the relevant structures trivial.

Fixes
* Make MXS_LRADC depend on INPUT to avoid compile failures. This fixes an
  issue introduced in the previous pull in this cycle.
