sound: soc: tegra: Fix Tegra210 I2S Fsync Polarity

The 'normal' polarity of the fsync is dependent on the audio format.
For example, for I2S the 'normal' polarity for the fsync is
falling-edge/low, where as for r/l-justified or dsp modes A/B it is
rising-edge/high. This is detailed in the Tegra210 TRM in the table
titled "Programming I2S to Operate in Various Modes" and also in
the Linux kernel header file for include/sound/soc-dai.h.

The Tegra210 i2s driver always assumes that the fsync is low for
'normal' polarity and high for 'inverted' polarity and does not
account for the audio format. Correct the Tegra210 I2S driver to
set the polarity according the the audio format.
