Add missing "jedec, spi-nor" compatible string for QSPI flash node. Spi-nor framework uses this compatibility string to probe & initialize flash. With missing compatibility string we are observing below error:

Zynq> sf probe 0 0 0 jedec_spi_nor spi_flash@0:0: unrecognized JEDEC id bytes: 00, 00, 00 Failed to initialize SPI flash at 0:0 (error -2)
