The previous condition is used to cross check only the active
stream status for I2S HS instance playback and capture use cases.

Modified logic to invoke sequence for two i2s controller instances.

This also fixes warnings reported by kernel robot:
"warning: variable 'frmt_val' set but not used"
"warning: variable 'reg_val' set but not used"
