[PATCH 4/4] arm64: dts: qcom: sc7180: disable quad mode for spi nor

[Hsin-Yi Wang]

Some of the SKUs are using gigadevice gd25lq64c flash chip. The chip
default enables quad mode, which results in the write protect pin set to
IO pin. In trogdor platforms, we won't use quad enable for all SKUs, so
apply the property to disable spi nor's quad mode.
