ASoC: SOF: topology: pass volume min/max linear value to FW
The driver currently passes the volume ramp type and length topology tokens to firmware, but the min and max volume are not set. This patch provides a correction to convert the information from the topology file and pass the linear volume min/max value to the firmware to improve transitions.
