msm: pm2: Call appropriate irq functions for 7k and 8625 targets

There is a difference between the 7k & 8625 targets interrupt
controllers. 7k & 8625 targets uses the VIC & QGIC controllers
respectively. Power driver uses these conrtoller API's to take
a decision while entering into low power modes. This change
provides a generic implementation wihtout worrying about the
interrupt controller being used on the target.
