[PATCH v2 5/8] ARM: dts: exynos: Remove DMA controller bus node name to fix dtschema warnings

[Krzysztof Kozlowski <krzk@kernel.org>]

There is no need to keep DMA controller nodes under AMBA bus node.
Remove the "amba" node to fix dtschema warnings like:

    amba: $nodename:0: 'amba' does not match '^(bus|soc|axi|ahb|apb)(@[0-9a-f]+)?$'

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

---

Changes since v1:
1. Remove the bus, as suggested by Marek
