Currently audio mclk uses a fixed clk of 11.2896MHz (multiple of 44.1kHz).
Replace this fixed clk with the programmable versa3 clk that can provide
the clocking to support both 44.1kHz (with a clock of 11.2896MHz) and
48kHz (with a clock of 12.2880MHz), based on audio sampling rate for
playback and record.
