Yan, Like 1bf2fc342a hv: pirq: refactor irq num alloc/free 
This commit refactors the alloc/free irq num, two functions are defined:
- uint32_t alloc_irq_num(uint32_t irq)
  - if irq is valid, mark the irq_desc as used; if it's IRQ_INVALID,
    alloc a free irq, or else do nothing;
  - return: irq num on success, or IRQ_INVALID on failure.

- void free_irq_num(uint32_t irq)
  - free the irq num allocated via alloc_irq_num();

And a global spinlock to protect it from concurrent allocation/free.
