5.15-stable review patch. If anyone has any objections, please let me know.

From: Wentao Liang vulab@iscas.ac.cn
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.
