arm64: dts: fvp/juno: Fix bus node names

Most Arm Ltd. boards are employing a layered bus structure, to map
the hardware design (SoC, motherboard, IOFPGA) and structure the DTs.

The "simple-bus" nodes only allow a limited set of node names. Switch
to use *-bus to be binding compliant.

This relies on a pending dt-schema.git fix for now:
