SDHI also had numerous problems with H3 ES1. The agreement was: If it is
"easily" upstreamable, then we want to support ES1 as much as possible.
If it is complex and a maintenance burden, then we don't upstream it.
This is why ES1 has no HS400 support for eMMC. It would have involved
activating the SDHI sequencer which we don't use otherwise.

I copied this behaviour and think it makes sense (for upstream).
