This variable is confusingly named, the different Linux IRQs
aren't any more virtual than any other Linux IRQ. Give it a
non-misleading name.

The data structure of_match_ptr() protects is always compiled in.
Hence of_match_ptr() is not needed.

In case request_threaded_irq inside adnp_irq_setup fails, the driver
segfaults. This is because irq_domain_remove is called twice with
the same pointer. First time in adnp_irq_setup and then a second time
after leaving adnp_irq_setup in the error path of adnp_i2c_probe
inside adnp_teardown.
This fixes this by removing the call to irq_domain_remove from
adnp_irq_setup.

CONFIG_HOTPLUG is going away as an option so __devexit is no

This commit adds a driver for the Avionic Design N-bit GPIO expander.
The expander provides a variable number of GPIO pins with interrupt
support.
Changes in v2:
- allow building the driver as a module
- assign of_node unconditionally
- use linear mapping IRQ domain
- properly cleanup IRQ domain
- add OF device table and annotate device tables
- emulate rising and falling edge triggers
- increase #gpio-cells to 2
- drop support for !OF
- use IS_ENABLED to conditionalize DEBUG_FS code
Changes in v3:
- make IRQ support runtime configurable (interrupt-controller property)
- drop interrupt-controller and #interrupt-cells from DT binding
- add inline to_adnp() function to wrap container_of() macro
- consistently use adnp as name for struct adnp variables
- remove irq_mask_cur and rename irq_mask to irq_enable
- fix a subtle deadlock in adnp_gpio_direction_output()
- remove dynamic allocations from debugfs code
- rename regs to num_regs to avoid confusion
- annotate non-trivial code with comments
- don't acquire mutex in adnp_gpio_get()
- assume NO_IRQ == 0
