Similar to the internal temperature sensor of the stm32
this driver controls the Vbat monitoring in Volts,
using an ADC internal input and the stm32-vbat node of the DTS.
The ref voltage is given by the ADC.
Note that stm32F1x does not propose the feature.

Add LINKER_KEEP macro which can be used to prevent linker garbage
collector from removing unused symbol (function or variable).
Example use case is to use it for functions which are part of a test
application which has functions which are indirectly called by the
host test tools. Since they are not called explicitely by the
application so without marking them with LINKER_KEEP they would be
removed by the linker garbage collector.

MISRA C:2012 Rule 21.13 (Any value passed to a function in <ctype.h>
shall be representable as an unsigned char or be the value EOF).
Functions in <ctype.h> have undefined behavior if they are called with
any other value. Callers affected by this change are not prepared to
handle EOF anyway. The addition of these casts avoids the issue
and does not result in any performance penalty.

The driver returns -EIO when a pin to be disconnected was not earlier
configured as input or output, what is not in line with the GPIO API.
This commit changes the driver to return 0 in such case.
Also -EIO is incorrectly returned when an interrupt trigger cannot be
configured in the nrfx_gpiote driver. This commit corrects this value
to -EINVAL.

This is a follow-up to commit f301dc2382.
Add missing GPIO_ACTIVE_LOW flag to sw_pwm channel definitions for
nRF51 DK and nRF51 Dongle so that the initial state of their PWM
outputs is properly set up.
Add missing sw_pwm channel definition in the nrf52833dk_nrf52820 target
that was modified in 793362ae5a instead
of in f301dc2382. Add also the pwm-led0
alias for its PWM LED so that it can be used with standard samples.

Add `status = "okay";` in `arduino_spi` to make sure the node is

Assign proper pins and add the arduino_spi node label to one SPI node
so that shields that require SPI can be used with the nRF9160 DK.
Due to the limited resources of the nRF9160 SoC, the arduino_spi (spi1)
and arduino_serial (uart1) interfaces cannot be used together on this
board, so remove the default "okay" status from the arduino_serial node
(this status is supposed to be set in a shield overlay that uses this
interface).
The spi1 node was selected as arduino_spi because:
- spi0 could not be used together with uart0 that is used by the Zephyr
console
- spi2 could not be used together with i2c2, which is arduino_i2c and
in newer nRF9160 DK revisions (0.14.0+) also provides communication
with the onboard GPIO expander
- spi3 is used in newer nRF9160 DK revisions for communication with the
onboard flash chip

Zephyr adds a custom handler that overrides the weak function
sys_arch_reset when TF-M platform partition is enabled.
This takes away the option for the application to override the weak

A full second is too much, and since "Ack local interrupt before
processing IPC" patch, it doesn't seem necessary. This whole second
wait would break tests that log too much content, as the firmware
is already running during the reset - and the host script wouldn't read
the contents, thus some of the logs would be overwritten.
