Add support for an optional "idle disconnect" feature in the TCA954x
I2C multiplexer. When enabled via the `i2c-mux-idle-disconnect` device
tree property, the driver will disconnect all channels after each
transfer. This helps avoid address conflicts when multiple multiplexers
are present on the same I2C bus.
Even if the I2C transfer fails, the driver will still attempt to
disconnect the channels to ensure the bus is left in a consistent state.
If the disconnect operation itself fails, its error code will be returned
unless the transfer already failed with a different error.
This implementation is inspired by the Linux kernel driver for PCA954x
I2C multiplexers. Special thanks to Ofir Shemesh for valuable suggestion.

The WDOG and IADC clock node definitions were missing for xg22,
and interrupt numbers were wrong for WDOG on xg27.

Downgrading interrupt priority for non critical interrupts for the
supported SOCs.
Previously almost all interrupts were at level 0 i.e. meaning no interrupt
had priority over the others. In reality only radio interrupts are critical
while others can be served with less haste.
Now the level zero is reserved for interrupts that need higher priority
than the radio without bypassing irq locks (zero-latency interrupts)
Level 1 for radio and levels 2 and 3 for rest of the services.

Replace occurrences of "RaspberryPi" with "Raspberry Pi" in
documentation, comment blocks etc. Correct the name of "PicoW" to
"Pico W", matching Raspberry Pi's documentation at
https://www.raspberrypi.com/documentation/microcontrollers/pico-series.html .

Remove redundant descriptions in RTC bindings, such
as "... node", "... common bindings" and "This binding provides".

The nRF SPIS peripheral is not an SPI controller but an SPI target
device, so its binding should not include "spi-controller.yaml"
(and so far it did, through "nordic,nrf-spi-common.yaml").
Fix this so that it is no longer possible to incorrectly add child
DT nodes as "devices" on the SPIS "bus" and then for example misuse
the SPI_CONFIG_DT() macro for such constructs.
Since this requires a small correction in the "overrun-character"
property in "nordic,nrf-spi-common.yaml", improve also its description
by adding there information from the corresponding property from
"spi-controller.yaml".

On STM32 USB, there are currently four types
of maximum-speed: "super-speed", "high-speed",
"full-speed" and "low-speed" (if present).
To simplify the driver, add maximum-speed if
not present as a dts property.

ULPT nodes:
- Added `ulpt0` at 0x40220000 (channel 0).
- Added `ulpt1` at 0x40220100 (channel 1).
- Included timer sub-nodes with `renesas,ra-ulpt-timer` compatibility.
Power state nodes:
- `stop0`: Runtime idle state mapped to LPM sleep mode.
- `stop1`: Standby state mapped to LPM software standby mode.
