PCM bottom layer simplification. pcm_rec_peak_addr variable no longer has to be handled there. Driver can just return current pointer for recording peaks. A new define, HAVE_PCM_REC_DMA_ADDRESS, specifies that physical addresses are being used for recording and translation is needed before starting a new block. The drivers need not worry about aligning start and size nor should care if either will be zero. All this will be checked in the logical layer first.
