This also cleans up a lot of crud in this driver:
1) Don't touch the BBC regs, just leave the watchdog trigger
behavior whatever the firmware programmed it to.
2) Use WATCHDOG_MINOR instead of hardcoded and not properly
allocated RIOWD_MINOR.
Hey, I haven't touched it since I wrote it years ago :-)

Various pieces of code around the kernel want to be able to trigger an
orderly poweroff. This pulls them together into a single
implementation.
By default the poweroff command is /sbin/poweroff, but it can be set
via sysctl: kernel/poweroff_cmd. This is split at whitespace, so it
can include command-line arguments.
This patch replaces four other instances of invoking either "poweroff"
or "shutdown -h now": two sbus drivers, and acpi thermal
management.
sparc64 has its own "powerd"; still need to determine whether it should
be replaced by orderly_poweroff().
