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.
