ARM: OMAP: Pass logical DMA channel number always to callback handlers
This makes parameter passing to DMA handlers uniform between non-chained and chained transfers and makes debugging easier. Additional data like chain_id can be always passed to handlers via callback data if needed. Signed-off-by: Jarkko Nikula <jarkko.nikula@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
