From: Padmavathi Venna <padma.v@xxxxxxxxxxx>
This patch adds dma controller node info on Exynos5420.
Exynos5420 has adma for audio IPs. As adma clk is dependent
on audss clk provider that will be added later.

Change since V2:
- Removed adma node as adma clock is dependent audss clock provider.
Changes since V1:
- In V1, dma node common stuff was added in common exynos5.dtsi file.
This was removed as per Kukjin comment and added in exynos5420.dtsi.
