When switching input/sensor the s_power() callback must be called for old sensor drivers to power on the new sensor and power off the previous sensor. atomisp_s_input() already does this but atomisp_link_setup() did not do this. Add a new atomisp_select_input() helper which does this and use this in both atomisp_s_input() and atomisp_link_setup() for consistent behavior. Also make atomisp_link_setup() turn the sensor back off when a link gets disabled.

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.
