The npcm driver has a bunch of references to the irq_chip parent_device
field, but never sets it.
Fix it by fishing that reference from somewhere else, but it is
obvious that these debug statements were never used. Also remove
an unused field in a local data structure.

Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().

The only usage of these structs is to assign their address to various
ops fields in the pinctrl_desc struct, which are const pointers. Make
them const to allow the compiler to put them in read-only memory.

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.
