vmemmap: generify initialisation via helpers
Convert the common vmemmap population into initialisation helpers for use by architecture vmemmap populators. All architecture implementing the SPARSEMEM_VMEMMAP variant supply an architecture specific vmemmap_populate() initialiser, which may make use of the helpers. This allows us to clean up and remove the initialisation Kconfig entries. With this patch there is a single SPARSEMEM_VMEMMAP_ENABLE Kconfig option to indicate use of that variant.
