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. This fixes uniprocessor configurations for some MIPS SMP systems.
