Yan, Like 2c044e0c4e hv: pirq: refactor vector allocation/free ... This commit refactors vector allocation/free codes, two functions are defined to help alloc/free vectors for an irq: - uint32_t alloc_irq_vector(uint32_t irq) - alloc a free vector (0x20 ~ 0xDF), and bind it to irq, for legacy irqs and static mapped irqs, vector has been allocated and bind, so just check the mapping correctness; - return: valid vector on success, VECTOR_INVALID on failure. - void free_irq_vector(uint32_t irq) - free vector allocated via alloc_irq_vector(), for legacy irqs and static mapped irqs, nothing need to do.
