[PATCH] bsp/leon3: Replace the define LEON3_MP_IRQ with a weakly linked variable

[Daniel Cederman]

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.
