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.
