[PATCH V9 7/8] powerpc: Check arch.vec earlier during boot for memory features

[Michael Bringmann]

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.
