98d9bc13cd mfd: Convert max8925 to new irq_ API
The genirq infrastructure is being converted to pass struct irq_data rather
than an irq number to irq_chip operations, update max8925 to the new APIs.

2d95ae3bbf input: Monitor both onkey up and down event
Remove original 3-second ONKEY event. Detect ONKEY changing event directly.
So both UP and DOWN event of ONKEY in max8925 are monitered.

90182317a9 mfd: Fix max8925 irq control bit incorrect setting
In max8925_irq_sync_unlock(), irq control bit is set at the same time.
Zero means enabling irq, and one means disabling irq.

The original code is:
	irq_chg[0] &= irq_data->enable;

It should be changed to:
	irq_chg[0] &= ~irq_data->enable;

Otherwise, irq control bit is mess.

68e488d965 mfd: Delay to mask tsc irq in max8925
There're two IRQ pins output from MAX8925. One is PMIC interrupt, the other
is TSC interrupt. But they're sharing one irq chip.

After initializing MAX8925 interrupts, unexpected TSC interrupt may occur and
it can't be cleared if touch driver isn't loaded.

Now move the operation of masking TSC interrupt behind requesting PMIC
interrupt. If touch driver isn't loaded, this interrupt is always masked.
