mtd: spi-nor: fsl-quadspi: fix unsupported cmd when run flash_erase
Erase function will use cmd 0x20 (SPINOR_OP_BE_4K) if kenrel enable option CONFIG_MTD_SPI_NOR_USE_4K_SECTORS. This command is not in fsl-quadspi driver LUT. So driver continue report fsl-quadspi 21e0000.qspi: Unsupported cmd 0x20. This patch fix this issue.
