The early_pfn_valid() macro is defined by it is never used.
Remove it.

Think the last user was removed with

commit 73a6e474cb376921a311786652782155eac2fdf0
Author: Baoquan He <bhe@redhat.com>
Date:   Wed Jun 3 15:57:55 2020 -0700

    mm: memmap_init: iterate over memblock regions rather that check
each PFN

    When called during boot the memmap_init_zone() function checks if
each PFN
    is valid and actually belongs to the node being initialized using
    early_pfn_valid() and early_pfn_in_nid().

Acked-by: David Hildenbrand <david@redhat.com>
