I left it, as this file is still not 2-clause SPDX tagged.

On another SoC revision, the capability register marks HS400 support
as enabled. However the interface itself is powered with 3.3V and it
turned out that my flags in SdMmcOverride driver did not cover this
case, which resulted in an unsuccessful EmmcSwitchToHS400 () execution
- it shouldn't be done at all.

Well done on keeping this tag. But I'm thinking we need to do that
relicensing sooner rather than later, and drop the tag.

However, can you clarify what problem this solves?

Ensure that in case of SlowMode or 3.3V operation,
also the HS400 capability will be disabled in the
SdMmc driver.
