include: pinctrl.h: Make PINCTRL_SKIP_SLEEP available with CONFIG_PM

Browse source 
In some cases, PINCTRL_STATE_SLEEP may be required even when
CONFIG_PM_DEVICE is not defined.
One example is the possibility/need to put JTAG pins to analog when
CONIG_PM=y and CONFIG_DEBUG=n.

the compiled firmware. However, there are some cases where certain states will
be conditionally used depending on a compilation flag. A typical case is the
``sleep`` state. This state is only used in practice if
:kconfig:option:`CONFIG_PM_DEVICE` is enabled. If a firmware variant without device
power management is needed, one should in theory remove the ``sleep`` state from
Devicetree to not waste ROM space storing such unused state.
:kconfig:option:`CONFIG_PM` or :kconfig:option:`CONFIG_PM_DEVICE` is enabled.
If a firmware variant without these power management configurations is needed,
one should in theory remove the ``sleep`` state from Devicetree to not waste ROM
space storing such unused state.
States can be skipped by the ``pinctrl`` Devicetree macros if a definition named
``PINCTRL_SKIP_{STATE_NAME}`` expanding to ``1`` is present when pin control
