The TI SimpleLink SDK got updated to version '4.40.04.04' in 'hal_ti'.
This introduced renames of some functions in HAL and has to be reflected
in Zephyr drivers which make use of them.
This renames 'PRCMPowerDomainStatus' to 'PRCMPowerDomainsAllOn' in all
affected 'cc13xx_cc26xx' drivers.

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.

The SSD16xx uses a separate pin to indicate if an SPI transfer is a
command or data. This means that driver needs to split most SPI
transactions into two distinct transactions, one for commands and one
for data. The driver currently doesn't request SPI_HOLD_ON_CS which
means that the chip select will be released momentarily between the
command and data phase.
Update the driver to request SPI_HOLD_ON_CS and SPI_LOCK_ON to lock
the bus and complete both phases of a command in one atomic operation.

Allow the battery voltage to be read through the ADC even if the
CONFIG_STM32_VBAT driver is not enabled.
I guessed this part of code is conditionally compiled depending on
CONFIG_STM32_VBAT because this feature, and hence the
LL_ADC_CHANNEL_VBAT constant is not available on all families. As the
feature is already checked at runtime (as the same driver supports
multiple instances), we can conditionally compile it depending on
LL_ADC_CHANNEL_VBAT instead.

This commit adds support for the ds18b20 1-wire temperature sensor.
The sampling resolution of the sensor can be set in DT.
In case only a single device is on the bus, the driver issues
skip_rom commands. However, in case DT defines several devices,
the driver will use match_rom commands and therefore it is necessary
to set the rom_id of the device via the sensor attribute interface before
being able to sample sensor values.

The zephyr-serial w1 driver introduced in this commit implements
all routines for the w1 api on top of the zephyr serial driver.
W1 bit read, write, and reset operations are executed by issuing
polling zephyr serial byte read and write operations.
The driver should be usable on most platforms in zephyr that have
implemented support for the polling procedures of the serial driver.
As not all serial drivers are implemented exactly the same minor
additional quirks may be needed on some platforms.
The most notable difference of polling serial driver implementations
seems to be that some return immediately from poll_out after the
transmission was started(e.g. STM32) and others wait until
the transmission was completed before returning from poll_out
(e.g. NRF). While this has influence on the timeout, both types
are supported by this driver because the driver waits for a
configurable time period until it terminates the read.
The driver needs an appropriate open drain interface to be able
to communicate with slaves.
In the simpliest case this might be achived by configuring the mcu pins
in open-drain configuration with a (sufficiently small) pull-up to 3V3/5V.
Otherwise an external circuit needs to provide this interface.
Overdrive and Standard Speed modes are supported by this driver.
