Add the Switch Register Access Block which is a special piece of hardware allowing us to perform indirect read/writes towards the integrated BCM5301X Ethernet switch. We also add the 4 Gigabit MAC Device Tree nodes within the brcm,bus-axi bus node to get proper binding between the BCMA instantiated core and the Device Tree nodes. We will need that to be able to reference Ethernet Device Tree nodes in a future patch adding the switch ports layout.
