[coreboot] printk and side effects

[Myles Watson]

This is a reminder to myself in case it is obvious to everyone else:

It seems very difficult to guarantee that the removal/insertion of a print
statement has no other effects.

I printed out the location of a variable, and that changed where it was
stored (from a register to being placed on the stack)...

This might not be a traditional "side effect", but it changed the behavior
of the code and surprised me.

Thanks,
Myles
