ARM: dts: exynos: move exynos-bus nodes out of soc in Exynos4412

The soc node is supposed to have only device nodes with MMIO addresses,
as reported by dtc W=1:

  exynos4412.dtsi:407.20-413.5:
    Warning (simple_bus_reg): /soc/bus-acp: missing or empty reg/ranges property

and dtbs_check:

  exynos4412-i9300.dtb: soc: bus-acp:
    {'compatible': ['samsung,exynos-bus'], 'clocks': [[7, 456]], 'clock-names': ['bus'], 'operating-points-v2': [[132]], 'status': ['okay'], 'devfreq': [[117]]} should not be valid under {'type': 'object'}

Move the bus nodes and their OPP tables out of SoC to fix this.
Re-order them alphabetically while moving and put some of the OPP tables
in device nodes (if they are not shared).
