mtd: rawnand: meson: fix OOB available bytes for ECC
It is incorrect to calculate number of OOB bytes for ECC engine using some "already known" ECC step size (1024 bytes here). Number of such bytes for ECC engine must be whole OOB except 2 bytes for bad block marker, while proper ECC step size and strength will be selected by ECC logic.
