Compile handle_percpu_irq even for uniprocessor kernels

Compiling handle_percpu_irq only on uniprocessor generates an artificial special case so a typical use like:

  set_irq_chip_and_handler(irq, &some_irq_type, handle_percpu_irq);

needs to be conditionally compiled only on SMP systems as well and an alternative UP construct is usually needed - for no good reason.
