mtd: nand: sunxi: Add randomizer configuration before randomizer enable
In sunxi_nfc_hw_ecc_read_chunk(), the sunxi_nfc_randomizer_enable() is
called without the config of randomizer. A proper implementation can be
found in sunxi_nfc_hw_ecc_read_chunks_dma().
Add sunxi_nfc_randomizer_config() before the start of randomization.
Fixes: 4be4e03efc ("mtd: nand: sunxi: add randomizer support")
