This CL introduces the Power Switch Logic (PSL) pads which detect the
wake-up events and turn on/off core power supply (VCC1) for ultra-low
-power consumption in npcx device-tree file.
By adding PSL input-pad objects, psl_in1, psl_in2, and so on, into
'psl-in-pads' property and configuring their 'flag' properties, the
related driver will configure them via soc specific functions later.
For example, if PSL input 1 pad that is plan to detect a 'falling edge'
event, this property should be:
vsby-psl-in-list {
psl-in-pads = <&psl_in1>;
};
And the flag property in psl_in1 should change to
&psl_in1 {
flag = <NPCX_PSL_FALLING_EDGE>;
};

On stm32f1 series, in output mode, there is no way to enable
pull-up/down resistors.
Clean these settings from helper defines.
Additionally add helper define to shorten few lines.

Macro STM32_PINMUX and related definitions are not compatible with
stm32f1 series and then should not be provided in -common.h.
Move them to stm32-pinctrl.h

This patch adds the DT nodes and binding for the pinmux registers,
aka IOCON (I/O control), found on the LPC11U6x MCUs.

STM32 pin configuration comments where offset by 4 bits.
Fix this issue and make pin configuration settings
easier to read.

Add needed uart pinctrl configuration in pinmux node.
This is done thanks to <soc>-pinctrl.dtsi file matching
the <soc>.dtsi files
Populate stm32 f4 based boards dts files with references
to uart pinctrl nodes.
