pinctrl: moorefield: Replace kernel.h by what is actually being used

The kernel.h is a mess of unrelated things and we only used it
as a proxy to array_size.h, hence switch from former to the latter.

pinctrl: moorefield: Use BUFCFG_PINMODE_GPIO in ->pin_dbg_show()

Use explicit comparison to BUFCFG_PINMODE_GPIO instead of implying it.

pinctrl: moorefield: Fix open-drain pin mode configuration

Currently the pin may not be configured as open-drain in some
cases because the argument may be 0 for the boolean types of
the pin configurations. Fix this by ignoring the argument.

With that, allow to actually restore pin to the push-pull mode.

pinctrl: moorefield: Convert to use new memeber in struct intel_function

Convert driver to use generic data type and hence a new member in
the struct intel_function. No functional change intended.

pinctrl: intel: Add Intel Moorefield pin controller support

This driver adds pinctrl support for Intel Moorefield. The IP block
which is called Family-Level Interface Shim is a separate entity in SoC.
The GPIO driver, which supports this pinctrl interface, will be
submitted separately.
