iio: Add t5403 barometric pressure sensor driver
16-bit pressure and temperature sensor
the chip can do I2C and SPI, only the I2C interface is supported
by the driver at the moment
datasheet: http://www.epcos.com/inf/57/ds/T5400.pdf
application note: http://www.epcos.com/blob/993154/download/1/t5403-applicationnote.pdf
an out-of-tree driver targetting the input subsystem is at
https://github.com/unixphere/t5400, it was rejected here:
http://comments.gmane.org/gmane.linux.kernel.input/28107
v2: (thanks Hartmut Knaack)
* fix MODE_HIGH, equals 2
* check INT_TIME mask in write_raw()

iio: hid-sensors: Added Pressure Sensor driver
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.

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)

iio: Add a comment to about alphabetical order to Kconfigs and Makefiles
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.
