It can be done for every PCI configuration using OF properties.
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The SIMBA APB bridge is strange, it is a PCI bridge but it lacks
some standard OF properties, in particular it lacks a 'ranges'
property.

What you have to do is read the IO and MEM range registers in
the APB bridge to determine the ranges handled by each bridge.
So fill in the bus resources by doing that.

Since we now handle this quirk in the generic PCI and OF device
probing layers, we can flat out eliminate all of that code from
the sabre pci controller driver.

In fact we can thus eliminate completely another quirk of the sabre
driver.  It tried to make the two APB bridges look like PBMs but that
makes zero sense now (and it's questionable whether it ever made sense).
So now just use pbm_A and probe the whole PCI hierarchy using that as
the root.

This simplification allows many future cleanups to occur.

Also, I've found yet another quirk that needs to be worked around
while testing this.  You can't use the 'class-code' OF firmware
property, especially for IDE controllers.  We have to read the value
out of PCI config space or else we'll see the value the device was
showing before it was programmed into native mode.

I'm starting to think it might be wise to just read all of the values
out of PCI config space instead of using the OF properties. :-/

I'd like to thank John Stul and others for helping
me along the way.

A lot of cleanups fell out of this.  For example, the get_compare()
tick_op was totally unused, so was deleted.  And the most often used
tick_op members were grouped together for cache-friendlyness.

The sparc64 TSC is given to the kernel as a one-shot timer.

tick_ops->init_timer() simply turns off the privileged bit in
the tick register (when possible), and disables the interrupt
by setting bit 63 in the compare register.  The ->disable_irq()
op also sets this bit.

tick_ops->add_compare() is changed to:

1) Add the given delta to "tick" not to "compare"
2) Return a boolean which, if true, means that the tick
   value read after writing the compare value was found
   to have incremented past the initial tick value.  This
   mirrors logic used in the HPET driver's ->next_event()
   method.

Each tick_ops implementation also now provides a name string.
And we feed this into the clocksource and clockevents layers.
