Added usage id processing for Pressure Sensor. This uses IIO
interfaces for triggered buffer to present data to user
mode. This uses HID sensor framework for registering callback
events from the sensor hub.

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)

Keeping Makefile and Kconfig entries in alphabetical order usually works better
than just appending new entries at the end, since it reduces the amount of
conflicts. This patch adds a comment to the IIO Kconfig and Makefile files to
document that the entries should be kept in alphabetical order.
Also reorder those entries which weren't in alphabetical order yet.
