memblock: Replace memblock_find_base() with memblock_find_in_range()

memblock_find_base() is a static function with two callers in
memblock.c and memblock_find_in_range() is a wrapper around it which
just changes the types and order of parameters.

Make memblock_find_in_range() take phys_addr_t instead of u64 for
consistency and replace memblock_find_base() with it.
