arm64: support huge vmalloc mappings
As commit 559089e0a93d ("vmalloc: replace VM_NO_HUGE_VMAP with
VM_ALLOW_HUGE_VMAP"), the use of hugepage mappings for vmalloc
is an opt-in strategy, so it is saftly to support huge vmalloc
mappings on arm64, for now, it is used in kvmalloc() and
alloc_large_system_hash().
