Add the pinctrl driver for the Qualcomm Technologies QDF2xxx ARM64 SoCs,
which uses the Qualcomm Technologies TLMM pinctrl/gpio device.  This
driver is probed via ACPI and uses the pinctrl-msm.c backend driver.

This driver is intended to be used only an ACPI-enabled system.  As such,
UEFI will handle all pin control configuration, so this driver does not
provide pin control functions.  It is effectively a GPIO-only driver.

The "function" of the MPP driver was inherited from the GPIO driver, but the
differences between the two hardware blocks makes both the driver and the
device tree binding to be awkward.

Instead of overloading the "normal" function with various modes this patch
transposes the pinmux function to represent the three operating modes of the
MPP (digital, analog and current sink). The properties of pin pairing and DTEST
routing is moved to separate properties.

Assign pm_power_off() if we have the PS_HOLD functionality so
that we can properly shutdown the SoC. Otherwise, shutdown won't
do anything besides put the CPU into a tight loop. Unfortunately,
we have to use a singleton here because pm_power_off() doesn't
take any arguments. Fortunately there's only one instance of the
pinctrl device on a running system so this isn't a problem.

If the pin function controller (which can be a GPIO controller) is
instantiated before the interrupt controllers, due to the ordering in
the DTS, the irq domains for the interrupt controllers referenced by its
"interrupts-extended" property cannot be found yet:

    irq: no irq domain found for /interrupt-controller@e61c0000 !

As the sh-pfc driver accesses the platform device's resources directly,
it cannot find the (optional) IRQ resources, and thinks no interrupts
are available. This may lead to failures later, when GPIOs are used as
interupts:

    gpio-keys keyboard: Unable to claim irq 0; error -22
    gpio-keys: probe of keyboard failed with error -22

To fix this, add support for deferred probing to sh-pfc, by converting
the driver from direct platform device resource access to using the
platform_get_resource() and platform_get_irq() helpers.

Note that while this fixes the root cause worked around by commit
e4ba0a9b ("ARM: shmobile: r8a73a4: Move pfc node to work around
probe ordering bug"), I strongly recommend against reverting the
workaround now, as this would lead to lots of probe deferrals in drivers
relying on pinctrl. This may be reconsidered once the DT code starts
taking into account phandle dependencies during device instantation.
