Support subpage writes using a custom implementation of write_subpage. The driver loads the page into SRAM buffer using NAND_CMD_READ0, when the framework requests the NAND_CMD_SEQIN command. Then, the buffer is updated by the custom write_subpage implementation. Upon write, the controller calculates the hardware ECC across the whole page before programming the page.
This method saves transferring the whole page over the bus to the NFC IP, which would happen when using NAND_NO_SUBPAGE_WRITE.

As previously discussed, please explain why subpage writes make sense with this controller.
