mtd: rawnand: sunxi: Add randomizer configuration in sunxi_nfc_hw_ecc_write_chunk

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.
