Converted the console driver to use libchip/serial and added support

for the z85c30 found on the DMV177.  This effort started with the
console driver from the Radstone PPC2.  But some simplifications were
made in the hope that console.c can be made a shared file at some point
in the near future.

Split the debugio from console.  This was done so at some point in the
future printk support as is found in the pc386 BSP can be shared
across all BSPs.
