Please move the 'aliases' and 'chosen' node into the .dts files, these
are board specific, not SoC specific.

For chosen, please remove earlyprintk and debug, which don't normally
make sense unless you are debugging, and which will break in a multiplatform
kernel.

Please also add an "stdout-path = &uart3" property in chosen so that
earlycon can work. Note that earlycon is currently broken on arm32,
but we'll get there.
