For the mpc8349e-mitx this must be incorrect since there is no ISA?

That doesn't matter.  We want the code to be as common as possible.
The actual virtual IRQ value is irrelevant.  The OF code gives you a
virq number, and you just use that.  Any code or board design that
depends on any relationship between the virq and the hwirq is broken.

Essentially all that is needed is a 1:1 mapping hirq:virq since

Needed for who?

For now we simply define irq.h NUM_ISA_INTERRUPTS 0

This is a bad idea.  You will just break something else.
