Merge tag 's3c24xx-dma' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into next/drivers

From Kukjin Kim, this branch adds device-tree support to the DMA controller
on the older Samsung SoCs. It also adds support for one of the missing SoCs
in the family (2410).

The driver has been Ack:ed by Vinod Koul, but is merged through here due
to dependencies with platform code.
