This is the register layout of the litesd peripheral for the fusesoc
based Microwatt SoC.

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.
Cheers,
Matt
