When assigning mpp settings from static mpp modes to mpp groups,
we do not want any groups that have no supported setting for a
specific Kirkwood variant. However, when there is at least a
single supported setting, we need to assign the number of all
settings in this mode to grp->num_settings as we are reusing
the static modes table.

Changelog:
v1->v2:
- Chose a less intrusive fix by adding supp_settings variable
  instead of looping over the settings twice.

Patch applied with Aaro's Test tag.
