Hugetlbfs: Enable hugetlbfs for more systems in Kconfig.
As part of adding hugetlbfs support for MIPS, I am adding a new

varients don't yet support it, we can enable selection of HUGETLBFS on
a system by system basis from the arch/mips/Kconfig.

hugetlbfs is a filesystem backing for HugeTLB pages, based on
ramfs. For architectures that support it, say Y here and read
