memory hotplug: Update phys_index to [start|end]_section_nr
Update the 'phys_index' property of a the memory_block struct to be called start_section_nr, and add a end_section_nr property. The data tracked here is the same but the updated naming is more in line with what is stored here, namely the first and last section number that the memory block spans. The names presented to userspace remain the same, phys_index for start_section_nr and end_phys_index for end_section_nr, to avoid breaking anything in userspace. This also updates the node sysfs code to be aware of the new capability for a memory block to contain multiple memory sections and be aware of the memory block structure name changes (start_section_nr). This requires an additional parameter to unregister_mem_sect_under_nodes so that we know which memory section of the memory block to unregister.
