arm64: dts: marvell: espressobin-ultra: fix SPI-NOR config

BugLink: https://bugs.launchpad.net/bugs/1981864
[ Upstream commit 5202f4c3816b42e989f9cad49a73c7e88fba89f4 ]

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.
