Not sure if this is related to a problem I was having on imx7d.

I was also disabling runtime pm as you showed above to workaround a
USB modem detection problem.

Li Jun suggested I check for the over-current polarity description of
the devicetree.

Passing 'disable-over-current' or ''over-current-active-low' made the
issue go away.
