ASoC: SOF: add _D3_PERSISTENT flag to fw_ready message
Add a bit definition to the fw_ready message, to denote if the FW
supports the IMR (Isolated Memory Region) restoring feature.
If the bit is set, the driver can skip downloading the firmware again
during system resume or runtime resume.
Bump the ABI version to 3.19 to make it aligned with FW side.
