Subject: [PATCH 3/4] ARM: dts: exynos4: add node for PL330 MDMA1 controller

Add missing PL330 MDMA1 controller node to the device tree (DT).

[ Currently there is no problem with using 'non-secure' mdma1 address
  instead of 'secure' one on revision 0 of Exynos4210 SOC (as used by
  Universal C210 board) as this SOC revision is unsupported by DT. ]
