ARM: SAMSUNG: Remove unnecessary code for dma
This patch removes the usage of DMACH_DT_PROP and dt_dmach_prop from dma code as the new generic dma dt binding support has been added. Signed-off-by: Padmavathi Venna <padma.v@samsung.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
