Add new IIO modifiers to support power and energy measurement devices:
Power modifiers:

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.

tools: iio: iio_generic_buffer ensure alignment
The iio_generic_buffer can return garbage values when the total size of
scan data is not a multiple of the largest element in the scan. This can be
demonstrated by reading a scan, consisting, for example of one 4-byte and
one 2-byte element, where the 4-byte element is first in the buffer.
The IIO generic buffer code does not take into account the last two
padding bytes that are needed to ensure that the 4-byte data for next
scan is correctly aligned.
Add the padding bytes required to align the next sample with the scan size.

iio: Add IIO_DELTA_VELOCITY channel type
The delta velocity is defined as a piece-wise integration of
acceleration data. The delta velocity represents the linear velocity
change between two consecutive measurements and it
is measured in m / s (meters per second).
In order to track the total linear velocity change during a desired
period of time, simply sum-up the delta velocity samples acquired
during that time.
IIO currently does not offer a suitable channel type for this
type of measurements hence this patch adds it.
