asoc: tegra: utils: fix for multiple instances of extern1 clock.
The extern1 codec clock was not getting switched off whenever codec goes below BIAS_OFF level. Moreover, there were two instances of extern1 clock whenever codec was on. Reason behind this was that, those codecs for which probe function was called and were not present on board, turned on their extern1 clock, but clean up routine (for switch device register failure) was not able to turn off the clock. With this change, a conditional check is put to turn off the clock.
