Document our requirements for initialisation of the Scalable Matrix Extension (SME) at kernel start. While we do have the ability to handle mismatched vector lengths we will reject any late CPUs that can't support the minimum set we determine at boot so for clarity we document a requirement that all CPUs make the same vector length available.
