pinctrl: protect pinctrl_list add
commit 7b320cb1ed2dbd2c5f2a778197baf76fd6bf545a upstream.
We have few fedora bug reports about list corruption on pinctrl,
for example:
https://bugzilla.redhat.com/show_bug.cgi?id=1051918
Most likely corruption happen due lack of protection of pinctrl_list
when adding new nodes to it. Patch corrects that.
Fixes: 42fed7ba44e ("pinctrl: move subsystem mutex to pinctrl_dev struct")
