misc: lan966x_pci: Fix dtc warns 'missing or empty reg/ranges property'

Browse Source 
dtc generates the following warnings when building the LAN966x device
tree overlay (lan966x_pci.dtso):
  Warning (simple_bus_reg): /fragment@0/__overlay__/pci-ep-bus@0/cpu_clk: missing or empty reg/ranges property
  Warning (simple_bus_reg): /fragment@0/__overlay__/pci-ep-bus@0/ddr_clk: missing or empty reg/ranges property
  Warning (simple_bus_reg): /fragment@0/__overlay__/pci-ep-bus@0/sys_clk: missing or empty reg/ranges property

Indeed, related nodes are under the pci-ep-bus (simple-bus) which is not
correct.

Put them outside this node.
