Subject: [PATCH v3 1/3] arm64: dts: marvell: espressobin-ultra: fix SPI-NOR config

SPI config for the SPI-NOR is incorrect and completely breaking
reading/writing to the onboard SPI-NOR.

SPI-NOR is connected in the single(x1) IO mode and not in the quad
(x4) mode.
Also, there is no need to override the max frequency from the DTSI
as the mx25u3235f that is used supports 104Mhz.

Fixes: 3404fe15a60f ("arm64: dts: marvell: add DT for ESPRESSObin-Ultra")
