davinci_cpdma: Fix channel number written to teardown registers
chan->chan_num is 0..CPDMA_MAX_CHANNELS-1 for tx channels and CPDMA_MAX_CHANNELS..2*CPDMA_MAX_CHANNELS-1 for rx channels. However, the rx and tx teardown registers expect zero based channel numbering. Since the upper bits of the registers are reserved, the teardown also worked before, this patch is cleanup only.
