Change the default IRQs.
...
* Reserve IRQ 0 to be used as a "non-maskable interrupt" (NMI) in the
future.
* Use IRQ 2 for the LiteX. This matches the standard mor1k config which
connects the UART to IRQ 2.
This change is needed for Linux running on LiteX as it gets grumpy with
using IRQ 0 for anything other other than an NMI.

or1k: Use EXCEPTION_STACK_SIZE of 256bytes.
...
or1k defines a 128 byte "red zone" after the stack that can not be
touched by the exception handler.
We also need 128 bytes to store the 32 registers.

This tries to replicate the same setup as in the Windows buildsystem. We
