arm64: dts: vexpress: Move fixed devices out of bus node

The devicetree compiler complains when DT nodes without a reg property
live inside a (simple) bus node:
Warning (simple_bus_reg): Node /bus@8000000/motherboard-bus/refclk32khz
                          missing or empty reg/ranges property

Move the fixed clocks, the fixed regulator, the leds and the config bus
subtree to the root node, since they do not depend on any busses.
