ASoC: tegra-alt: get rid of i2s_soc_data

Browse Source 
soc_data structure for i2s appears to be redundant for following reasons.
 * is_soc_t210 is unused. For older kernels this was added to implement
   MBIST WAR, bug 200035860. WAR is not required for kernel > k4.4 and
   hence cleaned up as part of bug 2485656.
 * set_audio_cif and set_slot_ctrl point to the same functions for
   Tegra210 and Tegra186. Thus there is no need to have soc_data members
   for it.

Hence references to soc_data is removed from the i2s driver.

Bug 200503387
