arm64/mm: Unify CONT_PTE_SHIFT
CONT_PTE_SHIFT actually depends on CONFIG_ARM64_CONT_SHIFT. It's
reasonable to reflect the dependency:
* This renames CONFIG_ARM64_CONT_SHIFT to CONFIG_ARM64_CONT_PTE_SHIFT,
so that we can introduce CONFIG_ARM64_CONT_PMD_SHIFT later.
* CONT_{SHIFT, SIZE, MASK}, defined in page-def.h are removed as they
are not used by anyone.
* CONT_PTE_SHIFT is determined by CONFIG_ARM64_CONT_PTE_SHIFT.
