You guys need to get everything straigthen up when it comes to busing
and child nodes for bcm53101x.dtsi, why do we need a "simple-bus" node
here which overlaps in part with the brcm-bus-axi node's range?
The more I look at BCMA and how it gets used for a non-external WLAN
card, and the less I am convinced it brings anything useful to the game,
quite the contrary...
