This reverts commit f4071997f1de016780ec6b79c63d90cd5886ee83.
These extra EHL entries won't behave as expected without a bit more work
on the kernel side so let's drop them until that kernel work has had a
chance to land. Userspace trying to use these new entries won't get the
advantage of the new functionality these entries are meant to provide,
but at least it won't misbehave.
When we do add these back in the future, we'll probably want to
explicitly use separate tables for ICL and EHL so that userspace
software that mistakenly uses these entries (which are undefined on ICL)
sees the same behavior it sees with all the other undefined entries.
