The GR712RC uses irq 14 for the Ethernet core and one might not want to
use the same level for the inter-processor interrupts. Sharing level
with the IPI handler is also currently not supported by the leon3 bsp,
so Ethernet interrupts gets ignored if level 14 is used.

The LEON3_MP_IRQ define is used to pick the IRQ to be used by the
shared memory driver and for inter-processor interrupts. On some LEON3
systems, for example the GR712RC, the default value of 14 is not
suitable.
To make this value configurable from the application, it is replaced with
a weakly linked variable that can be overridden from the application.
I checked in the patch.
Why is the value 14 not suitable for GR712RC? I was able to run the
test suite with this and didn't notice problems.
