[PARISC] Update dino from parisc tree

[PARISC] Update dino from parisc tree

Fix card-mode Dino crashes on 725 (and probably other Snake) systems.
Dino was coming up in fatal mode after a warm reboot.  Resetting Dino
brings it out of fatal mode, so do that if the status register indicates
we're in fatal mode.  Since this was never observed on any later systems,
I presume firmware does this for us on those.
