[PATCH] 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.
