printk: Make static printk buffers available to nbcon
The nbcon boot consoles also need printk buffers that are available
very early. Since the nbcon boot consoles will also be serialized
by the console_lock, they can use the same static printk buffers
that the legacy consoles are using.
Make the legacy static printk buffers available outside of printk.c
so they can be used by nbcon.c.
