A syscon device is a device managing a memory region containing a set of
registers that are not cohesive enough to represent as any specific type
of device. We need a driver for that because several other drivers could
use the same region at the same time and we need to io-map the region at
boot for MMU enabled platforms.

Move GPIO devices clock handling in stm32_pin_configure function
which is also used in stm32_setup_pins.
Additionally, add device usability check to be sure gpio driver
was initialized before being used by pinmux pseudo driver.
Last, going from the assumption that GPIO devices should be
initialized before being used by pinmux, then there is no need
to enable clock in case CONFIG_PM_DEVICE_RUNTIME=n.

Add support for the STM32WL integrated radio, based on the sx1262. The
STM32WL implementation does not use any GPIO, and the signals are routed
to other units of the SoC and accessed with the ST HAL.

This adds support for controlling the SUBGHZSPI NSS line in STM32WL
devices. This is a special dedicated SPI port only connected to the
radio device internally, chip select happens through a bit in the PWR
module. Adding a special dt-property to identify the port, it all gets
built out on non-WL devices.
Deduplicate the existing dts bindings in the process, and add the new
one for the special spi with the new property.

Current impĺementation fails due to missing stop bit
when reading data. This fixes it and refactor the implementation
by adding k_busy_wait when waiting I2C bus completion.
Also, this implementation is based on esp-idf v3.0.
It will be refactored based on latest esp-idf v4.3 using proper
low level calls.

CRC16 was removed by simply decreasing length of the last fragment by 2.
This worked as long as last fragment was longer than 1 byte. If not,
then last fragment was corrupted (its length ended up being 65535),
leading to undefined behavior.
Fix CRC16 removal by utilizing recently introduced
net_pkt_remove_tail(), that properly handles multiple fragments.

Instead of waiting forever for the SPI transfer to complete, let's use
a timeout value and bail out if elapsed. The timeout value logic is,
xfer_len/frequency + tolerance
Tolerance value can be modified using a Kconfig symbol,
CONFIG_SPI_COMPLETION_TIMEOUT_TOLERANCE. It defaults to 200ms.
