Add filter bypass mode, which bypasses the low pass filter, high pass filter and disables/unregister the clock rate notifier. Currently a feature like bypassing the filter is not achievable straightforward and not very deductive. The user has to look through the code and call the set_lpf_3db_frequency and set_hpf_3db_frequency iio attributes from the user interface using the corner cases (freq > largest lpf supported by the part, respectively freq < smallest hpf supported by the part). Moreover, in such case of bypassing the filter, the input clock rate change might mess up things so we want to make sure that it is disabled. Also, the feature will help emphasizing the filter behavior, therefore adding it in the userspace will ease the charcaterization of the filter's effects when active/disabled. It was requested by users of the driver to ease the interaction with different configuration modes of the device.

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 Restructured Text 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.
