Certain Apple machines don't use the ranges property correctly,  
but the
workaround should not be applied on other architectures.  This patch
disables the workaround for non-powerpc architectures.

I'm half tempted to add it to the quirk list (which should really be
made generic) so I can disable it on more 'modern' powerpc as well.

Oh please oh please oh please yes do.

OTOH, it would be even better to just fix up the device tree in the
early platform code.  Quirks are for broken hardware; software, we
can fix.
