From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>
The Unpriv spec states:
| The Zvknhb and Zvbc Vector Crypto Extensions --and accordingly the
| composite extensions Zvkn, Zvknc, Zvkng, and Zvksc-- require a Zve64x
| base, or application ("V") base Vector Extension. All of the other
| Vector Crypto Extensions can be built on any embedded (Zve*) or
| application ("V") base Vector Extension.
Enforce the minimum requirement via schema.
