arm64: dts: marvell: cn9132-clearfog: disable eMMC high-speed modes 



Similar to MacchiatoBIN the high-speed modes are unstable on the CN9132
CEX-7 module, leading to failed transactions under normal use.

Disable all high-speed modes including UHS.

Additionally add no-sdio and non-removable properties as appropriate for
eMMC.
