MPIC on NXP (Freescale) P2020 supports following irq
ranges:
> 0 - 11 (External interrupt)
> 16 - 79 (Internal interrupt)
> 176 - 183 (Messaging interrupt)
> 224 - 231 (Shared message signaled interrupt)
We have to remove "irq_count" from platform code as platform
is given precedence over device-tree, while I think device-tree
should have precedence.
