mtd: spi-nor: fsl-quadspi: fix read error for flash size larger than 16MB
commit41fe242979
upstream. If the size of spi-nor flash is larger than 16MB, the read_opcode is set to SPINOR_OP_READ_1_1_4_4B, and fsl_qspi_get_seqid() will return -EINVAL when cmd is SPINOR_OP_READ_1_1_4_4B. This can cause read operation fail. Fixes:e46ecda764
