ASoC: wm8960: Remove bitclk relax condition in wm8960_configure_sysclk
The call sequence in wm8960_configure_clocking is

   ret = wm8960_configure_sysclk();
   if (ret >= 0)
        goto configure_clock;

   ....

   ret = wm8960_configure_pll();

configure_clock:
   ...

wm8960_configure_sysclk is called before wm8960_configure_pll, as
there is bitclk relax on both functions, so wm8960_configure_sysclk
always return success, then wm8960_configure_pll() never be called.

With this case:
aplay -Dhw:0,0 -d 5 -r 48000 -f S24_LE -c 2 audio48k24b2c.wav
the required bitclk is 48000 * 24 * 2 = 2304000, bitclk got from
wm8960_configure_sysclk is 3072000, but if go to wm8960_configure_pll.
it can get correct bitclk 2304000.

So bitclk relax condition should be removed in wm8960_configure_sysclk,
then wm8960_configure_pll can be called, and there is also bitclk relax
function in wm8960_configure_pll.

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.
