It was not possible to disconnect a pin using the nRF pinctrl driver.
That is, it was not possible to set PSEL to 0xFFFFFFFF (indicating pin
is not connected). This can be useful in certain scenarios, e.g. a
bootloader configures all signals of a certain peripheral but
application then needs to disconnect certain signals.
A new DT macro has been introduced to accomplish this:
NRF_PSEL_DISCONNECT. It can be used like this to explicitely disconnect
a peripheral signal:
```
&pinctrl {
uart0_default: uart0_default {
group1 {
psels = <NRF_PSEL(UART_TX, 0, 1)>,
<NRF_PSEL_DISCONNECTED(UART_RX)>;
};
};
};
```

This is a follow-up to commit fd07675574.
The above commit was supposed to introduce overriding of the S0S1
drive setting with S0D1 for TWI/TWIM peripherals, but since it did
not properly update the `nrf_pin_configure()` function (the `drive`
parameter was only added in the function signature, but then it was
not used...), the drive setting was in fact not overridden.
This commit corrects this embarrassing oversight.

It is frequent to find variable definitions like this:
```c
static const struct device *dev = DEVICE_DT_GET(...)
```
That is, module level variables that are statically initialized with a
device reference. Such value is, in most cases, never changed meaning
the variable can also be declared as const (immutable). This patch
constifies all such cases.

This CL introduces how to configure PSL (Power Switch Logic) pads
properties such as input detection mode/polarity, pin-muxing and so
on via pinctrl mechanism. It includes:
1. Add two pinctrl properties and their enums for PSL input
detection configuration.
psl-in-mode:
- "level"
- "mode"
psl-in-pole:
- "low-falling"
- "high-rising"
2. Add macro functions to get PSL input detection and pin-muxing
configurations from 'pinmux', 'psl-offset' abd 'psl-polarity'
properties.
Here is an example to configure PSL_IN2 as the PSL detection input and
its mode and polarity.
/* A falling edge detection type for PSL_IN2 */
&psl_in2_gp00 {
psl-in-mode = "edge";
psl-in-pol = "low-falling";
};
A device will be introduced later which uses this pinctrl node to
configure PSL input detection settings and how to turn off VCC1 power
rail by PSL_OUT.

Stop relying on <soc.h> to access HAL APIs. Use generic, per-API headers
instead. Note that <soc.h> has been left as is for now, since ARM MPU
relies on a fragile chain of includes/type definitions.
This change should improve compilation efficiency, as we no longer pull
APIs that are not needed. A similar approach is followed by STM32
drivers.

This is a follow-up to commit fd7633126e.
For some reason the above commit added several switch cases without
required break statements. In effect, the same pin could get assigned
to multiple signal lines in QDEC or QSPI peripherals if not all pins
were defined for them in devicetree, and consequently these peripherals
could not work properly.

Introduce Pin Function Controller for Renesas R-Car family.
This first implementation support to set a given pin as gpio
or peripheral (GPSR), to set a peripheral function to a
pin (IPSR), to set pull-up, pull-down (PUEN, PUD).
In addition this driver allows to set driving capabilies(DRVCTRL).
Pins are identified thanks to the per SoC binding for
pin definition which also contains pin alternate function
parameters.
Some pins can also have driving capabilities, some have bias
capabilities.
In order to find the correct bias and drive registers pfc_r8a77951.c
describes the different registers.
Each SoCs or package will need to define getters
for these registers: pfc_rcar_get_bias_regs() and
pfc_rcar_get_drive_regs().

Add initial support for nRF pin controller driver. The implementation in
this patch does not yet support any peripheral. Only states
representation and basic driver functionality is introduced.
Note:
The nrf_pin_configure function has been marked as __unused since it may
not be used in certain scenarios until all peripherals are supported by
the pinctrl driver. For example, if only UART/E is supported but the
board does not enable UART, the function will never get called. However,
that board will likely have other peripherals that will gain support in
the future.
