gpio: davinci: don't create irq_domain in case of unbanked irqs

The system may crash if:
- there are more than 1 banks
- unbanked irqs are enabled
- someone will call gpio_to_irq() for GPIO from bank2 or above

Hence, fix it by not creating irq_domain if unbanked irqs are enabled
and correct gpio_to_irq_banked() to handle this properly.
