powerpc: Fix unused function warning 'lmb_to_memblock'
This patch fixes the following warning: arch/powerpc/platforms/pseries/hotplug-memory.c:323:29: error: 'lmb_to_memblock' defined but not used [-Werror=unused-function] static struct memory_block *lmb_to_memblock(struct of_drconf_cell *lmb) ^~~~~~~~~~~~~~~ The only consumer of this function is 'dlpar_remove_lmb', which is enabled with CONFIG_MEMORY_HOTREMOVE, so move it into the same ifdef block.

boot all CPUs are online before RAPL is initialized. A possible fix would be to reintroduce the mess which allocates a package data structure in CPU prepare and when it turns out to already exist in starting throw it away later in the CPU online callback. But that's a horrible hack and not required at all because RAPL becomes functional for perf only in the CPU online callback. That's correct because user space is not yet informed about the CPU being onlined, so nothing caan rely on RAPL being available on that particular CPU. Move the allocation to the CPU online callback and simplify the hotplug handling. At this point the package mapping is established and correct. This also adds a missing check for available package data in the event_init() function.
