gpio: dwapb: Discard GPIO-to-IRQ mapping function

Browse Source 
Since GPIOlib-based IRQ-chip interface is now utilized there is no need in
setting up a custom GPIO-to-IRQ mapping method. GPIO-lib defines the
standard mapping method - gpiochip_to_irq(), which will be used anyway no
matter whether the custom to_irq callback is specified or not.
