mm/mmap: drop ARCH_HAS_VM_GET_PAGE_PROT

Now all the platforms enable ARCH_HAS_GET_PAGE_PROT.  They define and
export own vm_get_page_prot() whether custom or standard
DECLARE_VM_GET_PAGE_PROT.  Hence there is no need for default generic
fallback for vm_get_page_prot().  Just drop this fallback and also
ARCH_HAS_GET_PAGE_PROT mechanism.
