[PATCH 3/4 V5] Enable MSI support for MPC8610HPCD board

[Jason Jin <Jason.jin@freescale.com>]

This patch enable the MSI on 8610hpcd board.
Through the msi-available-ranges property, All the 256
msi interrupts can be tested on this board.

In this version:
Add a flag MPIC_BROKEN_FRR_NIRQS in mpic_alloc making the mpic use
irq_count instead of FRR[NIRQ] to initialize the interrupt controller.
So the hwirq num need to be changed.
