Subject: [PATCH 2.6.21-rt2] PowerPC: revert fix for threaded fasteoi IRQ handlers

Revert the change to the "fasteoi" type chips as after handle_fasteoi_irq() had
been fixed, they've become meaningless (and even dangerous -- as was the case
with Celleb that has been fixed earlier)...

The patch in question wasn't even initially accepted but then was erroneously
restored along with the TOD patch.  I've asked to revert it but to no avail,
so here's the formal patch to revert it at last...
