ARM: dts: renesas: condor: Enable SPI NOR fast-read

This board requires SPI NOR fast-read, otherwise the SPI NOR
access returns corrupted data. Enable the fast-read explicitly
in DT as it has been disabled in the MTD subsystem by commit
d008190920 ("mtd: spi-nor: Mask out fast read if not requested in DT")
