riscv_cpu_validate_set_extensions() will play a future role in
write_misa(). First we need to ensure that this function is validating
first and setting cfg values later. At this moment this is not the case
of the RVV validation.

Move RVV validation up. Leave the 'ext |= RVV' where it is - next patch
has plans for it.
