If anyone has any objections, please let me know. ------------------ From: Josua Mayer 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.
