The MSI interrupts use the 16 high doorbells, which are notified by using IRQ1
of the main interrupt controller.
The MSI interrupts were handled correctly for Armada-XP and Armada-370 but not
for Armada-375 and Armada-38x, which use chained handler for the MPIC.
This commit fixes that by checking proper interrupt number in chained handler
for the MPIC.
