mtd: nand: sunxi: Add randomizer configuration before randomizer enable

Browse Source 
commit 4a5a99bc79cdc4be63933653682b0261a67a0c9f upstream.

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.
