arm64: dts: marvell: cn9132-clearfog: disable eMMC high-speed modes
commit 48b51799a5461707705454568453618cdd7307f4 upstream.
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.
Fixes: e9ff907f4076 ("arm64: dts: add description for solidrun cn9132 cex7 module and clearfog board")
