6b651486f5 x86: pinctrl: Set up itss in the probe() method
At present the itss is probed in the ofdata_to_platdata() method. This is
incorrect since itss is a child of p2sb which itself needs to probe the
pinctrl device. This means that p2sb is effectively not probed when the
itss is probed, so we get the wrong register address from p2sb.

Fix this by moving the itss probe to the correct place.

a9331a3388 x86: pinctrl: Add multi-ACPI control
Add a Kconfig to control whether pinctrl is represented as a single ACPI
device or as multiple devices. In the latter case (the default) we should
return the pin number relative to the pinctrl device.

4916f4586e x86: pinctrl: Add a way to get the pinctrl reg address
At present we can query the offset of a pinctrl register within the p2sb.
For ACPI we need to get the actual address of the register. Add a function
to handle this and rename the old one to more accurately reflect its
purpose.

336d4615f8 dm: core: Create a new header file for 'compat' features
At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

61b29b8268 dm: core: Require users of devres to include the header
At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

74749f1e84 x86: Add a generic Intel pinctrl driver
Recent Intel SoCs share a pinctrl mechanism with many common elements. Add
an implementation of this core functionality, allowing SoC-specific
drivers to avoid adding common code.

As well as a pinctrl driver this provides a GPIO driver based on the same
code.

Once other SoCs use this driver we may consider moving more properties to
the device tree (e.g. the community info and pad definitions).
