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. Fixes: e9ff907 ("arm64: dts: add description for solidrun cn9132 cex7 module and clearfog board") Cc: stable@vger.kernel.org Signed-off-by: Josua Mayer <josua@solid-run.com> Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com>
