"4th set of IIO new drivers cleanups and fixes for the 3.9 cycle
+ a new spi helper function.

1) Introduce spi_sync_transfer and use it within IIO.  Originally
   it was envisioned that this nice little boilerplate replacement
   would go through the spi tree, but Grant Likely stated he'd
   prefer we take it through IIO as the example usecases were all
   in IIO (and are also in this pull request).  Note that given
   their may have been some unresolved elements related to the
   coccinelle element of the patch, that has been stripped out
   and will doubtlessly follow at a later date (along with
   lots of other patches for drivers elsewhere in the tree).

2) New Invensense MPU6050 driver.  This is stripped down to pretty
   much the basics from the original submission with the intent
   to build up all the fancy bits in an incremental (and hence
   reviewable fashion). It's been through a good few revisions
   so nice to finally merge this.

3) Change to iio_channel_get api to simplify device tree based
   mappings.  The actual mappings are currently under review.

4) Build fixes for !CONFIG_IIO_TRIGGER in the st_sensors driver.
   This one snuck past during review and testing but got picked
   up by Randy Dunlap in a randconfig build.

5) Some max1363 cleanups and enhancements.

6) Some comment fixes to make them coherent and comprehensible.

7) Trivial build warning fix in mxs-lradc"

Description:

		This is mounting matrix for motion sensors. Mounting matrix

		is a 3x3 unitary matrix. A typical mounting matrix would look like

		[0, 1, 0; 1, 0, 0; 0, 0, -1]. Using this information, it would be

		easy to tell the relative positions among sensors as well as their

		positions relative to the board that holds these sensors. Identity matrix

		[1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and device are perfectly

		aligned with each other. All axes are exactly the same.
