DDR PHY tuning must not be attempted for such operations; non-PHY DDR usage is unaffected. [0] Add CQSPI_NO_PHY_TUNING_WITH_ODDR_2B_ADDR quirk and check it in cqspi_am654_ospi_execute_tuning(). When the erratum applies, return 0 with read_op->max_freq cleared -- the op-skip signal that tells the caller to try another op variant.
