No real change except moving fdt walking code into the fdtwalk library.
Also update some constants for ARM virt and bump the load address to
make sure the FDT works. Turns out it had been missing for a while so it
was actually not finding it because the kernel was loaded too close to
the start of memory.
Almost nothing changes here except moving braces to the same line as the
function declaration. Everything else is largely whitespace changes and
a few dangling files with tab indents.
