Hi,

After adding 'supm' and 'sspm' we're finally ready to add official RVA23
support after adding a couple of trivial pieces:

- add ssu64xl, another 'named feature' for something that we already
  implement in TCG;
- declare RVB in RVA22U64. This is more a cosmetic change to make it
  straightforward to implement RVA23U64 as a child of RVA22.

Adding RVA23U and RVA23S is done in the same model as we did with RVA22
profiles, including a CPU for each of them for easier consumption.

Patches based on alistair/riscv-to-apply.next.
