[PATCH] sh: pte_mkhuge() compile fix for !CONFIG_HUGETLB_PAGE

Presently it is bogus to call pte_mkhuge() outside of the CONFIG_HUGETLB_PAGE
context, as the only processors that support _PAGE_SZHUGE do so in the
hugetlbpage context only (and this is the only time that _PAGE_SZHUGE is even
defined).  SH-2 and SH-3 do not support huge pages at all, and so it is not
possible to enable this.
