Avoid NULL dereference in printk() before libchip console initialized
With the addition of dynamically registered libchip serial devices, there is the need to be able to use printk() before the console driver has initialized the indirect pointer table. This lets printk() support routines call pass a control structure directly without a lookup through the uninitialized indirect one.
