    ASoC: amd: vg: fix for pm resume callback sequence
    
    [ Upstream commit 83b713619ee1b15e09eae11a92a7f3305534223d ]
    
    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"
