pinctrl: st: Annotate st_pinconf_dbg_show() as holding mutex

Browse source 
st_pinconf_dbg_show() unlocks and locks the pinctrl_dev mutex, so it
must be called by the pinctrl core with the mutex hold.  Annotate the
function with sparse __must_hold, so any changes in pinctrl locking will
be statically detected.
