There is a draft spec that defines how interrupts are supposed to be mapped
from one bus to another, down to the PIC and CPU interrupt line.
So far we don't implement that spec. But PPC64 Linux requires us to for PCI
devices. So let's create a map here.

time.
I finally managed to track things down and it seems like we're missing
some properties in several devices.
While at it, I also bumped the ESCC IRQs to 0x24 / 0x25, as that's what
qemu now maps them on.
This patch (plus the qemu set) gets PPC64 Linux booting with
console=ttyPZ0.

Expose NVRAM compatibility
Linux requires the NVRAM to expose a 'nvram,flash' compatibility
in the device tree. Let's expose it so it's happy.
v2 adds a NEWWORLD macro to protect nvram,flash getting exposed in
oldworld macs.
