AMBA is a bus so name the node with DMA controllers just as "bus" 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>Do we really need a separate 'bus' for those DMA controllers? IMHO they are not different from the hw perspective from the other devices available on the SoC. A separate bus is a historical thing, they work fine when moved directly under the 'soc' node. The separate bus only mimics the way Linux organizes its drivers. This comment affects both ARM and ARM64.
