Split sti softc in two structures, one device-related for regular device

attachment and interface, one screen-attached for the real work.

The attachment code is now required to decide whether sti_end_attach() is
run immediately, or as a startuphook.

This allows hp300 to initialize sti early, and use it as a console; hppa
is functionally unchanged, as it uses the PROM console until the root device
is mounted.
