powerpc/mem: Add back missing header to fix 'no previous prototype' error 

Commit b26e8f2725 ("powerpc/mem: Move cache flushing functions into
mm/cacheflush.c") removed asm/sparsemem.h which is required when
CONFIG_MEMORY_HOTPLUG is selected to get the declaration of
create_section_mapping().

Add it back.
