ARM: S5PC100: DMA: Add platform devices for PL330 DMACs
Samsung's Soc S5PC100 has three PL330 DMACs. First is dedicated for Memory->Memory data transfer while the other two meant for data transfer with peripherals. Define and add latter two PL330 DMACs as platform devices on the S5PC100 platform. Signed-off-by: Jassi Brar <jassi.brar@samsung.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
