MI2S and DMA control registers are not volatile, so remove these from volatile registers list. Registers reset state check by reading non volatile registers makes no use, so remove error check from cpu and platform trigger callbacks. Initialized map variable two times in lpass platform trigger API, so remove redundant initialization.
