mtd: spi-nor: fsl-quadspi: fix read error for flash size larger than 16MB
commit 41fe242979e463d6ad251077ded01b825a330b7e 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.
