ASoC: xlnx: Disable clock wizard usage in audio driver

Current solution which uses clocking wizard, couldn't generate
accurate clock due to inability of clock wizard driver to program
fractional value of clock divider value. This is resulting in audio
loss in a simulataneous capture and playback audio usecase.
This patch disables its usage.
