onenand: Replace ONENAND_IS_MLC() with ONENAND_HAS_4KB()
This replacement causes 4KB page size devices to work properly with u-boot.
The old ONENAND_IS_MLC() behavior has been preserved by explicit
setting of ONENAND_HAS_4KB_PAGE for those devices.
This change makes the onenand_base.c file more resembling the respective
kernel sources.
