hal: Add support for BCL feature in sm6150

Add a new persist node to check whether BCL is
enabled or not to differentiate from legacy VBAT
feature. Use this node to select the VBAT sound
devices. BCL does not need any calibration unlike
legacy VBAT, use BCL persist node and avoid
sending calibration.
