ARM: dts: s5pv210: remove DMA controller bus node name to fix dtschema warnings

[ Upstream commit ea4e792f3c8931fffec4d700cf6197d84e9f35a6 ]

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

  amba: $nodename:0: 'amba' does not match '^([a-z][a-z0-9\\-]+-bus|bus|soc|axi|ahb|apb)(@[0-9a-f]+)?$'
