[PATCH v2 0/6] riscv: named features riscv,isa, 'svade' rework

[Andrew Jones]

Hi,

This is a bundle of fixes based on discoveries that were made in the
last week or so:

- what we call "named features" are actually real extensions, which are
  considered to be ratified by the profile spec that defines them. This
  means that we need to add riscv,isa strings for them. More info can be
  found on the commit msg of patch 2;

- the design behind 'svade' and 'svadu' is wrong. 'svade' does not mean
  'we do not have svadu'. In fact they can coexist. Patch 5 gives more
  details about it.


After this series, 'svade' is promoted to a regular extension and all
the named features QEMU implements are now being displayed in riscv,isa.

v2:
 - Ensure svade is off by default even for the max cpu type
