Add P9 DIO interrupt support
On P9 there are GPIO port 0, 1, 2 for GPIO interrupt, and DIO interrupt
is used to handle the interrupts.
Add support to the DIO interrupts:
1. Add dio_interrupt_register(chip, port, callback) to register the
interrupt;
2. Add dio_interrupt_deregister(chip, port, callback) to deregister;
3. When interrupt on the port occurs, callback is invoked, and the
interrupt status is cleared.
