ASoC: pandora: fix CLKX polarity
After mass production started it was found that several boards exhibit noise problems during sound playback. After some investigation it was determined that CLKX polarity is set incorrectly, and even if most boards can tolerate the wrong setting, there are some that don't. Fix polarity setup in the board file. As the clock settings for input and output now match, merge in and out functions and structures to simplify code.
