Yeah, we would need smp_processor_id() but not sure about the other
functions. There aren't many processor-related functions that Rust
drivers directly need to call, I guess.

Fine by me, I'll go with cpu.rs in the next version.

I chose processor.rs just because the C side uses processor.h for
cpu_relax() but cpu.rs also looks good.
