These have no dependencies on the EBUS probing layer, the clients
setup the registers and all of those details. The EBUS DMA layer
just programs and manages the DMA controller found in EBUS.

In order to convert EBUS drivers doing DMA into pure OF drivers,
we need the of_device->dev.archdata setup properly.
EBUS instances that can provide DMA for device nodes sit on PCI,
so detect and propagate the information there.

This thing was a mess, who wrote this junk? :)
Luckily we'll soon have nice generic I2C layer drivers for this PCF
based I2C stuff on sparc64.

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 :-)

As we convert the various by-hand sparc64 RTC drivers to use the
generic RTC framework and drivers, we need to keep the NTP
set_rtc_mmss() support via update_persistent_clock() working.
In the end, after all the RTC device cases are converted, this
local set_rtc_mmss() function will be deleted.

Add Sparc to the Kconfig depends list.
Add __sparc___ to address_sparc = 128 ifdef.
Finally, don't be concerned about 24-hour BCD mode support if the RTC
doesn't have a valid IRQ. We won't even use the alarm code in this
case and the Sparc RTCs have this limitation.

In order to make this week I also had to add an include
of linux/dma-mapping.h to asm/pci_32.h because drivers/pci/pci.c
really depends upon getting this header somehow.

The individual SBUS IOMMU arch code now sets the IOMMU information
directly into the OF device objects.

Add a helper function that, given a bus of_device node, propagates
all iommu, stc, and host_controller values down to the child nodes.

32-bit sparc just needed it to register the ioport procfs bits, do this
via an arch_initcall() instead.

No drivers or code uses this stuff any more, every driver has been
converted over to OF device probing.

This lets us kill this "map it in every IOMMU" crazy code, and also
some of the final references to sbus_root.
