Introducing IRQ_PER_PROC constant in the tsar boot loader
(pre-loader).
This constant is used to know how many XICU irq outputs
are connected to each processor.

i.e.

IRQ_PER_PROC = 3
NPROCS=2

xicu.irq_out[0] -> proc0 xicu.irq_out[3] -> proc1
xicu.irq_out[1] -> proc0 xicu.irq_out[4] -> proc1
xicu.irq_out[2] -> proc0 xicu.irq_out[5] -> proc1

This change the way the mailboxes for each processor
are calculated in the reset.S file.
