[PATCH v3 8/8] mtd: spi-nor: fsl-quadspi: fix unsupported cmd when run flash_erase

[Frank.Li at freescale.com]

From: Frank Li <Frank.Li at freescale.com>

fsl-quadspi 21e0000.qspi: Unsupported cmd 0x20

when config CONFIG_MTD_SPI_NOR_USE_4K_SECTORS enable,
erase will use SPINOR_OP_BE_4K, which was not supported by fsl-quadspi
driver
