Most of the nodes in e850-96 appended device tree that add bootph-all flags are not necessary. All those nodes are instantiated as dependencies of other nodes anyway. Remove those nodes to avoid cluttering the appended dts. 'bdinfo' reports 768 bytes reduction for "Early malloc usage", and 'dm tree' output doesn't change. Keep only pmu_system_controller changes, which are actually needed for serial to work properly.
