gen_isr_tables: Function ptr instead of (void *)

Browse source 
gen_isr_tables.py generates C-code which initializes a table with
values, and these values are structs with members cast to
(const void *) and (void *), respectively.

The actual struct definition has a member of type (const void *)
and another of type void (*)(const void *).

In order to avoid a large amount of reported issues in Coverity,
cast this to the exact type.
