[PATCH v2 0/2] powerpc/pseries: Auto-online hotplugged memory

Recent updates to the core mm code allow for auto-onlining of added
memory, commit id 31bc3858ea3. This update to the pseries hotplug
memory code takes advantage of this by setting the config option
CONFIG_MEMORY_HOTPLUG_DEFAULT_ONLINE=y so that we online added memory
by default, this maintains the current functionality, and removes
the code that explicitly onlines added memory.

Additionally the call to memblock_add() is removed, this is already
done in memory_add().

Changes from v1:
- The memhp_auto_online variable is no longer explicitly set.
- The patch is split into two patches
    1/2 - Update to us auto-onlining capabilities
    2/2 - Remove the call to memblock_add
