Now it even does not compile... I'm getting following error:

drivers/mtd/onenand/onenand_uboot.c: In function ‘onenand_init’:
drivers/mtd/onenand/onenand_uboot.c:37:31: error: ‘CONFIG_SYS_ONENAND_BASE’ undeclared (first use in this function)
  onenand_chip.base = (void *) CONFIG_SYS_ONENAND_BASE;
                               ^~~~~~~~~~~~~~~~~~~~~~~
drivers/mtd/onenand/onenand_uboot.c:37:31: note: each undeclared identifier is reported only once for each function it appears in

After I applied

Yes, that is possible. But then definition for partitions would be at
two places. Once in nokia_rx51_defconfig and second time in nokia_rx51.h
