6.12-stable review patch. If anyone has any objections, please let me know.

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.
