Grygorii Strashko 84f28998cc gpio: pcf857x: handle only enabled irqs
Now pcf857x_irq() IRQ's dispatcher will try to run nested
IRQ handlers for each GPIO pin which state has changed.
Such IRQs are, actually, spurious and nested IRQ handlers
have to be called only for IRQs wich were enabled by users.
This is not critical issue - just  /proc/interrupts
will display counters for unused IRQS:
399:          4          0   pcf857x   0 Edge
428:          1          0   pcf857x  13 Edge
430:          1          0   pcf857x  15 Edge

Hence, fix it by adding irq_enabled field in struct pcf857x to track
enabled GPIO IRQs and corresponding callbacks in pcf857x_irq_chip.

Similar functionality was presented in pcf857x driver, commit
21fd3cd187 ('gpio: pcf857x: call the gpio user handler iff...')

and then it was removed by commit
 a39294bdf4 ('gpio: pcf857x: Switch to use gpiolib irqchip...')
