The atclk is an optional clock for the CoreSight CATU, but the driver
misses to initialize it.
This change enables atclk in probe of the CATU driver, and dynamically
control the clock during suspend and resume.
The checks for driver data and clocks in suspend and resume are not
needed, remove them. Add error handling in the resume function.

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.
