Beware of revision 218075

[Marcel Moolenaar]

All,

Support for the MPC85xx development systems was broken 7 months ago
with initial support for G5 hardware and further regressed by the
support for FDT.

Revision 218075 has some sweeping changes related to the interrupt
framework, so please beware. Since I don't have G5 hardware it's
possible that G5 is broken due to it, so I appreciate getting a
thumbs up or thumbs down from anyone updating to 218075 or later.

I'll be causing some more churn in the coming weeks, but that
should be mostly related to the FDT support and as such should not
impact any powerpc platforms other than mpc85xx.

FYI,
