dt: Remove obsolete description of powerpc boot interface
32 and 64 bit powerpc support has been merged for a while now, but
the booting-without-of.txt document still describes 32 bit as not
supporting multiplatform, which is no longer true. This patch fixes
the documentation.
Also remove references to powerpc-specific details outside of section
I in preparation to add details for other architectures.
v3: cleaned up a lot more powerpc-isms and updated text to reflect current
usage conventions.
