registers (m, s, vs)
1x new system instruction (SCTRCLR)

I want to work on its IDL. When will PR #554 get merged. Should I create new yaml files for smctr/ssctr (to define config params) & sctrclr (to describe it in IDL) and leave out rest of the fields as they will be pushed by that PR?

Looking at it now, I think it just needs a rebase.
