mn88443x_cmn_power_on() did not handle possible errors of
clk_prepare_enable() and always finished successfully so that its caller
mn88443x_probe() did not care about failed preparing/enabling of clocks
as well.
Add missed error handling in both mn88443x_cmn_power_on() and
mn88443x_probe(). This required to change the return value of the former
from "void" to "int".

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.
