[RFC PATCH v2 2/2] arm64 Kconfig: Select gigantic page

[Xie Yisheng]

Arm64 supports gigantic page after
commit 084bd29810a5 ("ARM64: mm: HugeTLB support.")
however, it got broken by 
commit 944d9fec8d7a ("hugetlb: add support for gigantic page
allocation at runtime")

This patch selects ARCH_HAS_GIGANTIC_PAGE to make this
function can be used again.
