ARM: dts: imx6q-bx50v3: Add internal switch

Browse Source 
B850v3, B650v3 and B450v3 all have a GPIO bit banged MDIO bus to
communicate with a Marvell switch. On all devices the switch is
connected to a PCI based network card, which needs to be referenced
by DT, so this also adds the common PCI root node.
