hv: pirq: rename common irq APIs

Browse Source 
This commit cleans up the irq APIs which are a bit confusing.
 - pri_register_handler(), normal_register_handler() and
   common_register_handler() into request_irq(), and removed
   the unnecessary struct irq_request_info;
 - rename the unregister_common_handler() to free_irq();

After the revision, the common irq APIs becomes:
 - int32_t request_irq(uint32_t irq,
                    irq_action_t action_fn,
                    void *action_data,
                    const char *name)

 - void free_irq(uint32_t irq)
