Indeed, my serial debug patches are unrelated to this
early_serial_init() patch.

Mind you I think setting up the serial subsystem dynamically rather
than statically has the potential to make things a good deal neater
than the current maze of twisty little include files.

However there is a problem at the moment, because early_serial_init()
won't work if serial.o is compiled as a module.
