ARM: dts: s5pv210: move PMU node out of clock controller

[ Upstream commit bb98fff ]

The Power Management Unit (PMU) is a separate device which has little
common with clock controller.  Moving it to one level up (from clock
controller child to SoC) allows to remove fake simple-bus compatible and
dtbs_check warnings like:

  clock-controller@e0100000: $nodename:0:
    'clock-controller@e0100000' does not match '^([a-z][a-z0-9\\-]+-bus|bus|soc|axi|ahb|apb)(@[0-9a-f]+)?$'
