Antoniu Miclaus 70da020614 iio: add power and energy measurement modifiers
Add new IIO modifiers to support power and energy measurement devices:

Power modifiers:
- IIO_MOD_ACTIVE: Real power consumed by the load
- IIO_MOD_REACTIVE: Power that oscillates between source and load
- IIO_MOD_APPARENT: Magnitude of complex power

Signal quality modifiers:
- IIO_MOD_RMS: Root Mean Square value

Additionally adds:
- IIO_CHAN_INFO_POWERFACTOR: Power factor channel info type for
  representing the ratio of active power to apparent power

These modifiers enable proper representation of power measurement
devices like energy meters and power analyzers.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
