ASoC: tas2783-sdw: add firmware download status check
Currently, firmware download during system resume from suspend introduces
significant wake-up latency. However, since PRAM content in the AMP
persists across resets and is not erased, this step can be optimized.
By verifying that the firmware version read from registers matches the
expected value, we can confirm that memory content was retained.
Consequently, the PRAM download can be skipped, significantly reducing
resume latency.
