It changes some things in imx-ssi, sorry, perhaps I should have
splitted it into two patches.

admux clock does not seem to be a physical parent of the ssi clock, so
I don't think it should be a parent in the clock tree. But imx-ssi (or
some other evice) needs this clock to work. As mentioned in the other
response, I will put it directly into clk-imx35.c so this won't be a
patch for ASoC in the next version.
