ASoC: wm8962: Do not call configure_bclk() inside wm8962_set_dai_sysclk()

From: Fabio Estevam <[email protected]>

Currently after playing any audio file, we get the following error message:

$ aplay clarinet.wav 
Playing WAVE 'clarinet.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
$ wm8962 0-001a: Unsupported sysclk ratio 544

This error message appears about 5 seconds after the audio playback has finished.

Quoting Mark Brown [1]:

"The issue here is triggered by the machine
switching from the FLL to direct MCLK usage where the MCLK isn't generating a useful ratio.

I suspect we should just kill the configure_bclk() in set_sysclk(), that one isn't safe as we can't reconfigure a live SYSCLK and it's probably the one that generates your warnings."

Confirmed that the "Unsupported sysclk ratio" error message comes from wm8962_set_dai_sysclk(), so get rid of wm8962_configure_bclk() inside this function.

Applied, thanks.
