Fixes #1043

There were multiple issuese with DMI logging:

  1. Address was assumed to be the same (Stop assuming dmi.address is not changed in riscv_decode_dmi_scan() #1043).
  2. Reported IDLE count was not affected by a reset of the delays.
  3. VLA were used.

These issues are addressed in the commit.

  • The first just moves decode_dmi() and riscv_log_dmi_scan() functions.
  • The second addresses the issues outlined in the PR description.

Pedantic detail:

You can use fields[0].num_bits instead of fields->num_bits to make it clearer that fields is pointing to an array of items, not just a single item.

Suggested change
const unsigned int scan_bits = batch->fields->num_bits;
assert(batch->used_scans > 0);
const unsigned int scan_bits = batch->fields[0].num_bits;
