Select IRQ_DOMAIN_HIERARCHY for pmic-arb in Kconfig since this driver
uses the version 2 IRQ interfaces. IRQ_DOMAIN_HIERARCHY selects
IRQ_DOMAIN, so it can be removed from here.

Validation of the IRQ type was added to spmi pmic-arb, however spmi-mpp
in device tree still uses IRQ_TYPE_NONE. This commit caused the
spmi-mpp probe to fail since platform_irq_count() would return 0.
Correct this by backing out the previous patch.

Now that spmi-gpio is a proper hierarchical IRQ chip, and all in-tree
users of device tree have been updated, we can now drop the hack that
was introduced to disassociate the old Linux virq if a hwirq mapping
already exists. That patch was introduced to not break git bisect for
any existing boards.

Driver was tested using gpio-keys and iadc/vadc on the LG Nexus 5
(hammerhead) phone.

qpnpint_irq_domain_map did not validate the IRQ type and this can cause
IRQs to not work as expected if an unsupported type (such as
IRQ_TYPE_NONE) is passed in. Now that spmi-gpio is a hierarchical IRQ
controller, and all device tree bindings have been updated, add
additional validation to the type field.

Check to see if the hwirq is already associated with another virq on
this IRQ domain. If so, then disassociate it before associating the
hwirq with the new virq.

This is a temporary hack that is needed in order to not break git
bisect for existing boards. The next patch in this series converts
spmi-gpio to be a hierarchical IRQ chip, then there are several patches
to update all of the device tree files, and finally this patch will be
reverted within the same patch series.

IRQs for spmi-gpio are all initially setup without an IRQ hierarchy
on pmic-arb when mfd/qcom-spmi-pmic.c is probed (via the
devm_of_platform_populate call) due to the interrupts property in
device tree. Once spmi-gpio is converted to be a hierarchical IRQ chip
in the next patch, existing users of gpio[d]_to_irq() will call
pmic_gpio_to_irq(), and that will use the new IRQ chip code in
spmi-gpio that sets up the IRQ in an IRQ hierarchy. The hwirq is now
associated with two Linux virqs and interrupts will not work as
expected. This patch corrects that issue.

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.

Check the irq ownership in the irq_request_resources callback
instead of checking it during the irq mapping. This can prevent
installing the flow handler for the interrupt that is not owned by the EE
and allow the irq translation during the gpio driver probe.
