gpio: intel-mid: Move hardware initialization to callback

The driver wants to initialize related registers before IRQ chip will be added.
That's why move it to a corresponding callback. It also fixes the NULL pointer
dereference.

Fixes: 8069e69a9792 ("gpio: intel-mid: Pass irqchip when adding gpiochip")
