[PATCH v1 2/2] usb: musb: mpfs: detect UPLI external vbus control requirement from DT

[Conor Dooley]

The musb driver core already supports external vbus control for ULPI
PHYs, but none of the drivers actually enable it. A customer reported
needing this for their device, and now that a DT property for detecting
this configuration exists, read the property to enable the feature.
