sh: Fix hugetlbfs dependencies for SH-3 && MMU configurations.
The hugetlb dependencies presently depend on SUPERH && MMU while the hugetlb page size definitions depend on CPU_SH4 or CPU_SH5. This unfortunately allows SH-3 + MMU configurations to enable hugetlbfs without a corresponding HPAGE_SHIFT definition, resulting in the build blowing up. As SH-3 doesn't support variable page sizes, we tighten up the dependenies a bit to prevent hugetlbfs from being enabled. These days we also have a shiny new SYS_SUPPORTS_HUGETLBFS, so switch to using that rather than adding to the list of corner cases in fs/Kconfig.

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