Intel SST driver spews an info message "FW Versoin xxxx" at each time the device gets initialized. Since it's triggered at each PM (or even runtime PM), it appears so ofetn, and rather becomes annoying than useful.
This patch suppresses the superfluous messages by checking the currently loaded FW version with the previously loaded one.
