architecture.vec5 features: The boot-time memory management needs to know the form of the "ibm,dynamic-memory-v2" property early during scanning of the flattened device tree. This patch moves execution of the function pseries_probe_fw_features() early enough to be before the scanning of the memory properties in the device tree to allow recognition of the supported properties.
