Replace eswifi_gpio with gpio_dt_spec. We can replace devicetree
label based access with this change as we try and phase out the
usage of the 'label' property.

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.

spi_context_cs_configure_all() is currently called from
spi_bitbang_transceive(). This causes a glitch when combined with
SPI_HOLD_ON_CS is used.
Move the initialization to spi_bitbang_init which is what the other
SPI drivers seem to do.

The SPI bitbang driver doesn't correctly initialize the list of CS
GPIOs. As a consequence, SPI buses using the bitbang driver won't
drive CS low. Add the missing initialization.

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.

When an I2C transaction completes, the driver should clear all the FIFO
status. Otherwise, it has the chance to break the operation of the next
transaction. This commit sets the CLR_FIFO bit in the SMBFIF_CTS
register to clear all the FIFO status at the beginning of an I2C
transaction.

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.

This commit introduces a new api for the net layer of Dallas
1-wire protocol.
For single drop configurations w1_read_rom, and w1_skip_rom commands are
provided.
For multidrop configurations w1_match_rom, w1_resume_command,
w1_search_rom, and w1_search_alarm routines are provided as well.
Additionally, the reset_select routine, conditionally depending on the
bus configuration, either executes a match_rom, or a skip rom command.
A w1_write_read command simplifies the typical scenario of addressing
a device, writing a few bytes to the device and reading back the answer.
Additionally w1_crc8, and w1_crc16 are added as wrappers around the
zephyr in-tree crc8 and crc16_reflect implementations.
The former may be used to verify the validity of the rom id, while the
latter is used for integrity checking of many eeprom, and authenticator
commands.
The general search command does not support filtering on
the family code.
