Subject: sparseirq: make some func to be used with genirq

Impact: clean up sparseirq fallout on random.c

Ingo suggested to change some ifdef from SPARSE_IRQ to GENERIC_HARDIRQS
so we could some #ifdef later if all arch support genirq

irq_desc is defined in linux/irq.h, so include it in the genirq case.
