This is a bug fix. A pointer to the spi configuration is not saved when
the spi driver is configured for slave operation and it can lead to
runtime errors.

Sensor value unit is [m/s^2].
Currently calcs as [g/1000] unit.
Correcting calculation to convert [m/s^2].
Store the integer part to val1, and the fractional part to val2.

The regulator voltage should be set before the clocks are enabled.
This is especially the case when the MSIS at 48MHz is selected as
SYSCLK.

* Utilize DT_HAS_<COMPAT>_ENABLED for devicetree based drivers
* Move to using select I2C' instead of 'depends on'

Now that entropy drivers are enabled based on devicetree
we need to remove any cases of them getting enabled by
Kconfig.defconfig* files as this can lead to errors.

The waiting of the flag ARROK could be quite long (100µs-200µs in my
test). During this time, the interrupts are locked that is not
recommended. To avoid this, we manage the update of the autoreload value
in interruption

HCI message sending in this hci driver as these actions require hci_host
to be available and could be performed by the remote host if required.
Explicit this dependency using CONFIG_BT_HCI_HOST.
This is is required to be able to compile BT_HCI_RAW mode.

The def command Indicates that a comment block contains documentation
for a #define macro. This is useful if the comment block documents a
macro not adjacent to it, e.g.
```c
/**
* @def MAX(x,y)
* @brief Computes the maximum of @a x and @a y.
*/
#ifdef XXX
#define MAX(x,y) ...
#endif
```
However, it is not necessary if the comment is adjacent to the
definition, e.g.
```c
/**
* @brief Computes the maximum of @a x and @a y.
*/
#define MAX(x,y) ...
```
This patch removes all unnecessary def entries in-tree.

remove the TX thread, as this thread can become starved and unable to
reclaim TX buffers from the hardware. Instead reclaim buffers in ISR.
Change eth_tx function to first take from the tx_buf_sem, so that multiple
