The function sunxi_nfc_hw_ecc_write_chunk() calls the sunxi_nfc_hw_ecc_write_chunk(), but does not call the configuration function sunxi_nfc_randomizer_config(). Consequently, the randomization might not conduct correctly, which will affect the lifespan of NAND flash. A proper implementation can be found in sunxi_nfc_hw_ecc_write_page_dma().
Add the sunxi_nfc_randomizer_config() to config randomizer.
