ASoC: SOF: compress: Prevent current kernel running with older FW

After introducing extended parameters we need to forbid older firmware
versions to run with the current and future kernel versions.

Although in theory the communication protocol will still work the
semantics at application level are undefined. So, prevent this by
disallowing older firmwares to run with newer kernels.
