Ok. I've actually stumbled over missing declarations from of_platform.h
and related files a number of times. Could we please not hide any
declarations inside of #ifdef when there is no #else alternative?

If we just show the of_default_bus_match_table declaration in the
header file, there is no need to provide the silly NULL macro,
since the of_platform_populate alternative will just ignore it.

I'll just put the code in an #ifdef for now, but I'd really prefer
to clean up this and many other locations that currently have
to do #ifdef CONFIG_OF when they really don't need to.
