remove_pagetable() should only be called when CONFIG_MEMORY_HOTPLUG
is enabled to clean up the page table entries created when memory
was hot-added.

Currently On arm64, memory section size is hard-coded to 1G.
Make this configurable if memory-hotplug is enabled, to support
more finer granularity for hotplug-able memory.

When onlining memory blocks, this option helps to add the target
memory block to ZONE_MOVABLE zone type. For successful offlining,
these memory blocks should belong to 'ZONE_MOVABLE' since it carries
only movable pages. When this option is not set, the default zone
policy is to add the blocks to 'ZONE_NORMAL' which may pin pages.

To guarantee successful hot-plugging of memory blocks, these blocks
should belong to ZONE_MOVABLE which has migratable pages. Linux kernel
during boot initializes all the available memory blocks to ZONE_DMA and
ZONE_NORMAL. Hence, boot the system with less memory whose percentage
is given by mem-offline DT property 'mem-percent' and override any memory
limit imposed by kernel boot params and let mem-offline driver initialize
the remaining with ZONE_MOVABLE. The memory blocks in this zone are
applicable for memory offlining.

Section mapping is good for TLB. But sometimes, when
system is low on physically continuous memory, this can
cause memory allocation failures. Add a fallback option to
allocate vmemmap pages from discontinuous pages.
