    arm64/mm: Drop setting PTE_TYPE_PAGE in pte_mkcont()

    PTE_TYPE_PAGE bits were being set in pte_mkcont() because PTE_TABLE_BIT
    was being cleared in pte_mkhuge(). But after arch_make_huge_pte()
    modification in commit f819281 ("arm64/mm: Re-organize
    arch_make_huge_pte()"), which dropped pte_mkhuge() completely, setting
    back PTE_TYPE_PAGE bits is no longer necessary. Change pte_mkcont() to
    only set PTE_CONT.
