The early FDT scanning functions use of_scan_flat_dt() which implements 
its own node walking method. This function predates libfdt and is an 
unnecessary indirection. This series reworks 
early_init_dt_scan_chosen(), early_init_dt_scan_root(), and 
early_init_dt_scan_memory() to be called directly and use libfdt calls.

Ultimately, I want to remove of_scan_flat_dt(). Most of the remaining 
of_scan_flat_dt() users are in powerpc.

"checkpatch --strict" reports some "CHECK" issues, but review of the patches
for correctness becomes much more difficult if they are addressed, so they
should be ignored for this series.
