Sets the chip to be master over LRC
and BCLK
0=BCLK and LRC clock are inputs
1=BCLK and LRC clock are outputs
generated by the WM8976 (MASTER)
Configures the BCLK output frequency,
for use when the chip is master over
BCLK.

Sets the scaling for either the MCLK or
PLL clock output (under control of
CLKSEL)
000=divide by 1

Controls the source of the clock for all
internal operation:
0=MCLK
1=PLL output
