x86: use proper types for interrupt callbacks

The mainboard_interrupt_handlers() argument for the function
    pointer was using void * as the type. This does not allow the compiler
    to catch type differences for the arguments. Thus, some code has been
    committed which violates the new interrupt callbacks not taking any
    arguments. Make sure the compiler provides a type checking benefit.
