We had floated the idea of adding cpu_is_*() (Well, soc_is_*()) macros
for Tegra in the past, and received the message that was a bad idea;
things should instead be driven by compatible flag values or similar.
See http://www.spinics.net/lists/linux-tegra/msg02250.html. That said,
I see many cpu_is_*() calls in arch/arm, so perhaps we should revisit
