Subject: [PATCH v2 07/10] gpio: dwapb: Discard ACPI GPIO-chip IRQs request

Since GPIOlib-based IRQ-chip interface is now utilized there is no need
in calling the methods acpi_gpiochip_{request,free}_interrupts() here.
They will be called from gpiochip_add_irqchip()/gpiochip_irqchip_remove()
anyway.
