The config stuff was already in drivers/watchdog/Kconfig

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 :-)

This thing was completely pointless.
Just find the OF device in the parent of drivers that want to program
this device, and map the DMA regs inside such drivers too.
This also moves the dummy claim_dma_lock() and release_dma_lock()
implementation to floppy_32.h, which makes it handle this issue
just like floppy_64.h does.

This has been marked BROKEN for a long time and it's more likely
to get rewritten from scratch than to be fixed up and made usable.

This converts all instances of bus_id in the sparc core kernel to use
either dev_set_name(), or dev_name() depending on the need.
This is done in anticipation of removing the bus_id field from struct
driver.

Fully unify all of the DMA ops so that subordinate bus types to
the DMA operation providers (such as ebus, isa, of_device) can
work transparently.
Basically, we just make sure that for every system device we
create, the dev->archdata 'iommu' and 'stc' fields are filled
in.
Then we have two platform variants of the DMA ops, one for SUN4U which
actually programs the real hardware, and one for SUN4V which makes
hypervisor calls.
This also fixes the crashes in parport_pc on sparc64, reported by
Meelis Roos.

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().
