#1205229 — [PATCH 16/19] phy-sun4i-usb: Only check vbus-det on power-on on boards with vbus-det

From: Hans de Goede <hdegoede@redhat.com>

data->vbus_det is always 1 on boards without a (working) vbus-det, skip
the vbus_det test on such boards.

This fixes the sun4i usb phy code never turning on Vbus on such boards.
