ASoC: SOF: amd: remove unused sha dma interrupt code

During initial development time for RN platform, when SHA
dma gets completed, SHA DMA engine used to raise the ACP interrupt.
In ACP interrupt handler, SHA DMA interrupt got handled.
Currently SHA DMA compleition is verified by checking
transfer count using read poll time out logic.
Remove unused SHA dma interrupt handling code.
