Third set of fixes for IIO in the 3.13 cycle.

* Fix for a bug in the new cm36651 driver where it told the IIO driver it
  was providing a decimal part, but then didn't.  Now it correctly tells the
  IIO core that it is only providing an integer value.  This prevents random
  incorrect values being output on a sysfs read.

* 3 fixes where drivers were miss specifying the endianness of their channels
  as output through the buffer interface.  These were discovered whilst
  removing the terrible IIO_ST macro once and for all.  The result is that
  userspace may be informed that the buffer elements are being output as
  little endian (on little endian platforms) when infact they are big endian.
  Thus userspace will handle them incorrectly.  This incorrect buffer
  element specification is provided as sysfs attributes under
  iio:deviceN/scan_elements.
