[ Upstream commit 75fd6485cccef269ac9eb3b71cf56753341195ef ]
While support for working with a vbus was added, the regulator was never
actually gotten (despite what was documented). Fix this by actually
getting the supply from the device tree.
Fixes: 7acc9973e3c4 ("usb: phy: generic: add vbus support")
