msm: mpm: MPM driver support for devicetree/irqdomain
The current MPM driver works for targets where the interrupt controllers
operate in a legacy mode, where the linux irqs are at a constant offset
from the hardware irqs. On newer targets, the mapping within the
interrupt controllers are no longer restricted to legacy mode.
The change also address the interface changes in the MPM hardware
starting with 8974 chipsets.
