This makes the driver use the irqchip template to assign
properties to the gpio_irq_chip instead of using the
explicit call to gpiochip_irqchip_add().
The irqchip is instead added while adding the gpiochip.
Also move the IRQ initialization to the special .init_hw()
callback.

Modify omap_gpio_set_config() to handle pin config bias flags by calling
gpiochip_generic_config().
The pin group for the gpio line must have the corresponding pinconf
properties:
PIN_CONFIG_BIAS_PULL_UP requires "pinctrl-single,bias-pullup"
PIN_CONFIG_BIAS_PULL_DOWN requires "pinctrl-single,bias-pulldown"
This is necessary for pcs_pinconf_set() to find the requested bias
parameter in the PIN_MAP_TYPE_CONFIGS_GROUP pinctrl map.

Most other drivers fill out the gpio_irq_chip using a
struct gpio_irq_chip *girq helper variable for ease of
reading.
We also make a habit of explicitly assigning NULL and
zero to the parent IRQs when using ordinary IRQ handlers
in the driver, mostly for code readability and
maintenance.

I noticed on Nexus 7 that after rebooting from downstream kernel to
upstream, the GPIO interrupt is triggering non-stop despite interrupts
being disabled for all of GPIOs. This happens because Nexus 7 uses a
soft-reboot, meaning that bootloader should take care of resetting
hardware, but the bootloader doesn't do it well. As a result, GPIO
interrupt may be left ON at a boot time. Let's mask all GPIO interrupts
at the driver's initialization time in order to resolve the issue.

This change addresses one of the GPIO-core TODOs for the MAX77620 driver
which requires modern drivers to use the irqchip template. Instead of
using the GPIO's irqchip-helpers for creating the IRQ domain, the
gpio_irq_chip structure is now filled by the driver itself and then
gpiochip_add_data() takes care of instantiating the IRQ domain for us.

The platform_get_irq() returns a positive interrupt number on success and
negative error code on failure (zero shouldn't ever happen in practice, it
would produce a noisy warning). Hence let's return the error code directly
instead of overriding it with -ENODEV.

The gpiochip_add_data() takes care of setting the of_node to the parent's
device of_node, hence there is no need to do it manually in the driver's
code. This patch corrects the parent's device pointer and removes the
unnecessary setting of the of_node.

Remove recalculation of offset from desc, where desc itself was calculated
from offset.
There is no benefit from the desc -> hwgpio conversion in this context.
The only implicit benefit of the offset -> desc -> hwgpio is
the range check in the offset -> desc, but where desc is required you
still get that, and where desc isn't required it is simpler to perform
the range check directly.

Kerneldoc expects struct properties to be documented using the syntax
'@.*: ', but no '@' has been provided in 'struct syscon_gpio_data's
header. Add them to stop confusing kerneldoc.
Fixes the following W=1 warnings:
drivers/gpio/gpio-syscon.c:48: warning: Function parameter or member 'compatible' not described in 'syscon_gpio_data'
drivers/gpio/gpio-syscon.c:48: warning: Function parameter or member 'flags' not described in 'syscon_gpio_data'
