Now only 3 USB phy drivers (phy-qcom-8x16-usb.c, phy-omap-otg.c and
phy-msm-usb.c) had registered an extcon, mostly did not.
phy-omap-otg.c did not add one usb phy, so I did not convert it.
phy-msm-usb.c had 2 separate extcon devices, but my last patch did not
support separate extcon devices which need to modify again. Moreover
in future usb phy drivers do not need to implement extcon things in
their own drivers.
