Added new field to struct gpio_keys_button: exclusive_irq which can
be used to specify whether driver wants to have exclusive access to
IRQ or can it be shared. By default IRQs for gpio-keys are shareable.

I think the idea makes sense with one exception - why limit just to
sharing and not let platform specify the exact IRQ flags it needs,
defaulting to IRQF_TRIGGER_RISING | IRQF_TRIGGER_FALLING | IRQF_SHARED?
