Hi,

In this version we're changing our minds w.r.t write_misa() and we're
now officializing it as a regular no-op. This was proposed as a better
alternative than trying to fix all the potential problems the code has
in the v3 review [1].

If we decide later on that there's a worthwhile use case to support,
where write_misa() needs to be (re-)implemented, we can use git to see
the code that has been removed and use it.

Changes from v3:
- patches without acks: 1 and 2
- patch 1:
  - reformulated: turn write_misa() into a proper no-op
- patch 2:
  - remove RISCV_FEATURE_MISA
