arm64: dts: freescale: imx93-phyboard-segin: Add USB vbus regulators

Browse Source 
Add USB vbus regulators to silence the following kernel warnings:

  usb_phy_generic usbphynop1: dummy supplies not allowed for exclusive requests (id=vbus)
  usb_phy_generic usbphynop2: dummy supplies not allowed for exclusive requests (id=vbus)

Because generic USB PHY driver requires exclusive vbus regulators since
commit 75fd6485cc ("usb: phy: generic: Get the vbus supply").
