Subject: [PATCH -v2 2/2] genericirq: change ack/mask in irq_chip to take irq_desc
 instead of irq



will have
void            (*ack)(struct irq_desc *desc);
void            (*mask)(struct irq_desc *desc);
void            (*mask_ack)(struct irq_desc *desc);
void            (*unmask)(struct irq_desc *desc);
void            (*eoi)(struct irq_desc *desc);

so for sparseirq with raidix tree, we don't call extra irq_to_desc, and could use desc directly

-v2: change all member of irq_chip to use desc only.
