iio: amplifiers: ada4250: add support for ADA4250

The ADA4250 is an instrumentation amplifier with SPI/pin-strap
progammable gains that is optimized for ultra-low power systems.
With a minimum supply voltage of 1.7V, 26uA of quiescent current,
a shutdown mode, a sleep mode, and a fast wake up settling time,
ADA4250 can be power cycled on a battery powered system for even
futher savings.

The ADL5240 is a high performance, digitally controlled variable gain
amplifier (VGA) operating from 100 MHz to 4000 MHz. The VGA integrates a
high performance, 20 dB gain, internally matched amplifier (AMP) with a
6-bit digital step attenuator (DSA) that has a gain control range of
31.5 dB in 0.5 dB steps with ±0.25 dB step accuracy.

iio: amplifiers: ad8366: Add support for the ADA4961 DGA

This change adds support for the ADA4961 BiCMOS RF Digital Gain Amplifier,
(DGA), which is optimized for driving heavy loads out 2.0 GHz and beyond.
The device typically achieves -90 dBc IMD3 performance at 500 MHz and
-85 dBc at 1.5 GHz.

Datasheet link:
http://www.analog.com/media/en/technical-documentation/data-sheets/ADA4961.pdf

This change re-uses the existing ad8366 driver, as most logic is similar.
Also, this chip has a reset pin which is initialized during probe.

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.
