These files are useless, they don't contain device nodes for anything 
other than the UARTs.  There is no existing system that has only UARTs 
and no other devices, so these files cannot be (and can never be) used 
anywhere.

Since the boot firmware in all real, and emulated, systems is supplying 
correct DTBs, we should consider not merging these files, and removing 
the likewise useless thunder-88xx.dts  thunder-88xx.dtsi
