[U-Boot Patch v2 3/4] dts: u-boot.dtsi: override flash tx-rx width

[Sagar Shrikant Kadam]

The hifive-unleashed-a00.dts has flash spi-tx/rx width set
to 4-bit mode. During sf probe, spi_nor_scan fails to read the
JEDEC ID with reg_proto set to SNOR_PROTO_1_1_1. Setting it to
1-bit mode as of now will help read the JEDEC-ID and perform other
flash operations.
