The npcmgpio_irqchip structure is only copied into another
structure, so make it const.
The opportunity for this change was found using Coccinelle.

We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.
For chained irqchips this is a pretty straight-forward
conversion.

devm_kasprintf() may return NULL on failure of internal allocation thus
the assignment to .label is not safe if not checked. On error
npcm7xx_gpio_of() returns negative values so -ENOMEM in the
(unlikely) failure case of devm_kasprintf() should be fine here.

Modify GPIO direction setting in pin configuration function by using
generic GPIO functions to set the GPIO direction instead of direct
access to the GPIO direction register.
