[PATCH] powerpc: enable irq's for platform functions.

Browse Source 
Make the platform function interrupt functions actually work.  Calls
irq_enable() for the first in the list, and irq_disable() for the last.

Added *func to struct irq_client so the the user can pass just that to
pmf_unregister_irq_client().
