pinctrl: denverton: Switch to use Intel pin control PM ops

The main driver conditionally exports the PM ops structure.
Switch this driver to use it instead of customly wrapped one.

pinctrl: denverton: Replace MODULE_ALIAS() with MODULE_DEVICE_TABLE()

As Krzysztof pointed out the better is to use MODULE_DEVICE_TABLE()
as it will be consistent with the content of the real ID table of
the platform devices.

pinctrl: denverton: Enable platform device in the absence of ACPI enumeration

This is to cater the need for non-ACPI system whereby
a platform device has to be created in order to bind
with the Denverton pinctrl platform driver.

pinctrl: intel: Switch to use exported namespace

We already have a few symbols exported in the namespace.
Let's do the same for others (except PM for now).

pinctrl: denverton: Update pin names according to v1.08

Version 1.08 of pin list has some changes in pin names for Intel Denverton.

Update the driver accordingly.

pinctrl: denverton: Provide Interrupt Status register offset

Since some of the GPIO controllers use different Interrupt Status offset,
it make sense to provide it explicitly in the driver.

pinctrl: denverton: Replace acpi.h with mod_devicetable.h

There is no need to include acpi.h since driver doesn't use anything from it
except the propagation of mod_devicetable.h.

Include latter directly instead.

pinctrl: denverton: Get rid of unneeded ->probe() stub

The local ->probe() stub does nothing except calling
a generic Intel pin control probe function. Thus,
it's not needed and generic function may be called directly.

Convert the driver accordingly.

pinctrl: intel: Move linux/pm.h to the local header

We now using a common macro for PM operations in pin control drivers for Intel
SoCs, and since that macro relies on the definition and macro from linux/pm.h
header file, it's logical to include it directly in pinctrl-intel.h. Otherwise
it's a bit fragile and requires a proper ordering of header inclusion in C
files.

pinctrl: intel: Add Intel Denverton pin controller support

This driver adds pinctrl/GPIO support for Intel Denverton SoC. The GPIO
controller is based on the same hardware design that is already used in
Intel Sunrisepoint so we leverage the core driver here.
