Convert the spmi-pmic-arb IRQ code to use the version 2 IRQ interface
in order to support hierarchical IRQ chips. This is necessary so that
spmi-gpio can be setup as a hierarchical IRQ chip with pmic-arb as the
parent. IRQ chips in device tree should be usable from the start without
the consumer having to make an additional call to gpio[d]_to_irq() to
get the proper IRQ on the parent.

The old qpnpint_irq_domain_map function would hardcode the handler as
handle_level_irq, however qpnpint_irq_set_type would later override the
handler. Properly set the handler when the IRQ is mapped. This new code
doesn't return an error for IRQ_TYPE_NONE and preserves the existing
behavior of using handle_level_irq since there are some broken device
tree bindings that need to be corrected first.

Driver was tested on a LG Nexus 5 (hammerhead) phone.

The broken device tree bindings are corrected in this patch series and
additional validation to the type field is added later in the series.

Changes since v5:
- Properly set handler to edge or level when the IRQ is mapped.

Changes since v4:
- None

Changes since v3:
- None

Changes since v2:
- Don't move pmic_gpio_of_match block. Use device_get_match_data instead
  of of_match_device.
- Correct build warning on arm64: warning: cast from pointer to integer
  of different size
