ASOC: Intel: kbl_rt5663_rt5514_max98927: Do not try to disable disabled clock 
In kabylake_set_bias_level(), enabling mclk may fail if the clock has
already been enabled by the firmware. Attempts to disable that clock
later will fail with a warning backtrace.

mclk already disabled
WARNING: CPU: 2 PID: 108 at drivers/clk/clk.c:952 clk_core_disable+0x1b6/0x1cf

Only disable the clock if it has been enabled.

README 

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.
