[PATCH 1/3] arm64: dts: qcom: ipq9574-rdp-common: Enable quad SPI mode for SPI-NAND

[Md Sadre Alam]

Set the SPI-NAND device node to use 4-bit transmit and receive bus widths.

The board supports quad SPI transfers, but the device tree currently does
not describe the wider bus. Add spi-tx-bus-width and spi-rx-bus-width so
the controller and flash can use quad mode instead of single-bit transfers.
