So it seems that the mac99 PIC is implemented correctly but has no interrupts registered.
I can't add anything to the interrupt question but for the other missing device tree properties like reservation-granule-size I've collected some links with dumps of the machine mac99 should try to emulate earlier here:
http://patchwork.ozlabs.org/patch/330550/Look at links in the patch comments, the actual patch was found not to be useful but the device tree dumps might serve as a reference to see how it looks on real hardware.
Unfortunately that's all I have now hoping it might help with some of those errors.
