ENGR00313685-3 of/irq: simplify args to irq_create_of_mapping

commit e6d30ab1e7d1281784672c0fc2ffa385cfb7279e upstream.

All the callers of irq_create_of_mapping() pass the contents of a struct
of_phandle_args structure to the function. Since all the callers already
have an of_phandle_args pointer, why not pass it directly to
irq_create_of_mapping()?
