Log Message:
Revise console device handling:
	* do not require a `zs' driver for console handling
	* run the console on PROM primitives until a device recognises
	  itself as a console device during normal autoconfiguration.
	* allow (keyboard) devices to take over the input channel of
	  the PROM primitive-based console device.

As a result, consinit() is much simplified and does no longer have
to "detect" devices to setup a working console device. This complexity
has moved to individual drivers which interpret the PROM information
after they have attached to decide whether or not to act as a console.
