Hello everyone,

Second version for adding support for the kx132-1211 accelerometer

KX132 accelerometer is a sensor which:
- supports G-ranges of (+/-) 2, 4, 8, and 16G
- can be connected to I2C or SPI
- has internal HW FIFO buffer
- supports various ODRs (output data rates)

The KX132 accelerometer is very similair to the KX022A.
One key difference is number of bits to report the number of data bytes that
have been stored in the buffer: 8 bits for KX022A vs 10 bits for
KX132-1211.

Changes in v2:
- added a new patch for warning when the device_id match fails in the
probe function
- added a new patch for the function that retrieves the number of bytes
in the buffer
- added a change to the Kconfig file in the patch adding the support
for the kx132-1211
- various fixes and modifications listed under each patch
