Andy Shevchenko 494a94e38d gpio: dwapb: Call acpi_gpiochip_free_interrupts() on GPIO chip de-registration
Add missed acpi_gpiochip_free_interrupts() call when unregistering ports.

While at it, drop extra check to call acpi_gpiochip_request_interrupts().
There is no need to have an additional check to call
acpi_gpiochip_request_interrupts(). Even without any interrupts available
the registered ACPI Event handlers can be useful for debugging purposes.
