In preparation for extending samples/sensor/magn_polling to support
additional magnetometer drivers, enable these drivers by default when
the sensor driver class is enabled (CONFIG_SENSOR=y) and a compatible
devicetree node is enabled.

The fxos8700 device supports 3 modes: accelerometer-only,
magnetometer-only, or hybrid (accelerometer and magnetometer) modes. The
accelerometer-only mode is register compatible with mma8451q, mma8652fc,
and mma8653fc, which allows the fxos8700 driver to be used with these
devices as well.
Most in-tree boards can use hybrid mode because they have the fxos8700
device, therefore we change the driver default to match the common case.
For the handful of boards that have an mma86xx or mma84xx device, we
override the driver default to accelerometer-only mode. As a result, we
can enable the magn_polling sample application for the fxos8700 driver
without having to add a bunch of board-specific configuration overlays
for hybrid mode.

According to the formulas found in the reference manuals of the SoC
families using the "st,stm32-temp-cal" version of the temperature sensor
(i.e. G0, G4, H7, L0, L1, L4, L5, U5, WB, WL), the temperature is
computed with the following formula:
T = ((TS_CAL2_TEMP - TS_CAL1_TEMP) / (TS_CAL2 - TS_CAL1))
* (TS_DATA - TS_CAL1) + TS_CAL1_TEMP
What is called ts-cal-offset in the stm32_temp driver is therefore the
same value as TS_CAL1_TEMP1. Use it directly instead of defining another
property.

The stm32_temp driver defines the ts-voltage-mv property to determine
the reference voltage of the ADC in the temperature computation. However
this information is already available in the device tree at the ADC
level (even with the same default value). Use it through the ADC API
instead of duplicating the information.

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.

The gpio_dev field of struct spi_cs_control is deprecated. The
driver was already using SPI_CONFIG_DT_INST, so we should be
using the associated gpio member of spi_cs_control.

Updates the API and types to match updated I2C terminology. Replaces master
with controller and slave with target.
Updates all drivers to match the changed macros, types, and API signatures.

This fixes a bug in the sm351lt driver whereby global triggering will

We get type mismatch errors because of use of K_MSEC. As the timeout
is defined in terms of milliseconds and k_uptime_get() returns
milliseconds we can just remove K_MSEC usage.

Move driver to use gpio_dt_spec for GPIO interrupt handling.
Added check to vcnl4040_trigger_set to handle case of trigger
mode enabled but the devicetree doesn't have an int_gpios property.
Also, moved up the checking/handling of gpio port device in
vcnl4040_trigger_init so that if we error out its before we
setup any threads and such.

The magnetometer data read from AK9863 is assumed to be big endian
(like the accelerometer & gyroscope data).
However it is in little endian, which means the appropriate byteorder
function is sys_le16_to_cpu().

Remove wrapper functions for getting i2c bus and i2c bus
