Subject: [RFT v2 36/48] genirq, arm: Kill the first parameter 'irq' of irq_flow_handler_t
Now most IRQ flow handlers make no use of the first parameter 'irq'.
And for those who do make use of 'irq', we could easily get the irq
number through irq_desc->irq_data->irq. So kill the first parameter
'irq' of irq_flow_handler_t.
To ease review, I have split the changes into several parts, though
they should be merge as one to support bisecting.
