The driver has no information on firmware version until the FW_READY
IPC, so we can't block the load. And with the firmware handling
happening in a work queue, blocking will not result in a failed probe.
IIRC those timing issues are only for the HDaudio link DMA, I don't
think we had issues with DMIC or SSP.
A warning urging people to update the firmware is probably easier to
implement.
