The register layout looks right, but the upstream litemmc driver also now
needs the property
clocks = <&sys_clk>;
(and associated sys_clk node).
"non-removable" has a typo, though I'm not sure we want non-removable anyway?
Most devices have a SD or microSD socket, and eMMC needs other driver litemmc
changes.
