pinctrl: mvebu: fix num_settings in mpp group assignment
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.
Fixes: 0581b16b1840 ("pinctrl: mvebu: complain about missing group after checking variant")
