These do not all strictly belong to the g1 core and even the majority
of previously documented bits were not used (yet) by the driver irq
handlers, but it's still very useful to have an overview of all IRQs,
especially since starting with core versions vc8000 and later the irq
bits previously used by G1 and G2 have been merged at the same address.
