I think not require. I will remove it.

There is no wake register. Here I kept for the incerease the wake conut 
so that irq_set_irq_wake() can be called.

I think it is also not correct after change
regmap: irq: initialize all irqs to wake disabled

I need to set the irq_wake(0 without the register.

There is 2 sets of registers which need to be configure, MASK and LINE 
enable.

regmap take care of mask only.
