memory-hotplug: remove memmap of sparse-vmemmap
Introduce a new API vmemmap_free() to free and remove vmemmap
pagetables. Since pagetable implements are different, each architecture
has to provide its own version of vmemmap_free(), just like
vmemmap_populate().
Note: vmemmap_free() is not implemented for ia64, ppc, s390, and sparc.
