 Host Controller

Hello,

I think this wording is still very confusing, and continues to cause
confusion.

We should just state that each Xenon controller supports a single slot,
and that's it.

The text still says "a single Xenon IP can support multiple slots",
which continues to cause confusion.

Best regards,
