It is just used as a parent to encapsulate two PBM objects.

But that layout is only really relevant and necessary for
psycho PCI controllers, which unlike all the others share
a single IOMMU instance between sibling PCI busses.

Use rtc subsystem for sparc32 architecture.
Actually, only one driver is needed: m48t59
as it supports the most common clocks on sparc32
machines: m48t08 and m48t02.

The device nodes that sit above 'esp' and 'le' on SBUS lack a 'ranges'
property, but we should pass the translation up to the parent node so
that the SBUS level ranges get applied.

Three main things:

1) Make prober an arch initcall instead of using hard-coded invocation
   from paging_init()

2) Shrink table size, the fpu ident stuff was never used.

3) Use named struct initialized in table.

While doing some easy cleanups on the sparc code I noticed that the
CONFIG_SUN4 code seems to be worse than the rest - there were some
"I don't know how it should work, but the current code definitely cannot
work." places.

And while I have seen people running Linux on machines like a
SPARCstation 5 a few years ago I don't recall having seen sun4
machines, even less ones running Linux.

This driver is now limited to just doing the basic clock board and FHC
chip initialization and registering the platform devices for the
per-board LEDs, which are driven by the new LEDS_STARFIRE driver.

The IRQ register handling is already confined purely to the device
tree code.

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.
