powerpc/pmi: Irq handlers return irqreturn_t

Commit bedd30d986a05e32dc3eab874e4b9ed8a38058bb ("genirq: make irqreturn_t
an enum") from the genirq tree in next-20090319 caused this new warning:

arch/powerpc/sysdev/pmi.c: In function 'pmi_of_probe':
arch/powerpc/sysdev/pmi.c:166: warning: passing argument 2 of 'request_irq' from incompatible pointer type

Change the return type of the handler from "int" to "irqreturn_t".
