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.
