Would you please remove CLK_SET_RATE_NO_REPARENT flag from here? Let me
know if you have reservations against this.

With RFC patches, I am able to do a clk_set_rate() on this clock to
get a 24MHz output to the codec clock. With this flag set, I again have
to rely on the default value set to this register in bootloader.
