We really shouldn't have this as a custom property, we should be using
a combination of the clock bindings.

In the driver this would turn into using clk_get() to get the MCLK, then
we can query the rate with clk_get_rate() and use option 0 or 1 if the
rate matches, or the PLL otherwise.  If we fail to get MCLK then we can
fall back to using BCLK.
