mm, hugetlb: use cma_declare_contiguous_multi

hugetlb_cma is fine with using multiple CMA ranges, as long as it can get
its gigantic pages allocated from them.  So, use
cma_declare_contiguous_multi to allow for multiple ranges, increasing the
chances of getting what we want on systems with gaps in physical memory.
