iio: hid-sensors: accelerometer: Add sensitivity

A number of Properties that can be applied to Data Fields are per data
field basis or for all data fields. Adding sensitivity field for all
accelerometer fields, which is most commonly used in currently
available sensor hubs.

iio: Add Freescale MPL3115A2 pressure / temperature sensor driver

I2C-controlled MEMS sensor with 20-bit pressure measurement (pascal) and
12-bit temperature measurement

driver only exposes basic functionality, see TODO remarks
datasheet: http://cache.freescale.com/files/sensors/doc/data_sheet/MPL3115A2.pdf

v2:
* store 20-bit value in 32-bit buffer element (instead of 24-bit)
* zero buffer to prevent kernel data leak to userspace
* fix mutex unlock in trigger handler (thanks Andi Shyti)
