[PATCH] ARM: zynq: Rename bus to be align with simple-bus yaml

[Michal Simek]

Rename amba to AXI. Based on Xilinx Zynq TRM (Chapter 5) chip is "AXI
point-to-point channels for communicating addresses, data, and response
transactions between master and slave clients. This ARM AMBA 3.0..."

Issues are reported as:
.. amba: $nodename:0: 'amba' does not match
'^([a-z][a-z0-9\\-]+-bus|bus|soc|axi|ahb|apb)(@[0-9a-f]+)?$'
>From schema:
../github.com/devicetree-org/dt-schema/dtschema/schemas/simple-bus.yaml

Similar change has been done for Xilinx ZynqMP SoC.
