coreboot: introduce commonlib

Instead of reaching into src/include and re-writing code
allow for cleaner code sharing within coreboot and its
utilities. The additional thing needed at this point is
for the utilities to provide a printk() declaration within
a <console/console.h> file. That way code which uses printk()
can than be mapped properly to verbosity of utility parameters.
