Add I2C and SPI bus communication routines in separate files,
and register one or the other as read/write callbacks based
on bus selection in DTS.
This commit is fixing issue #22348 as well, as the SPI part
is handling in the proper way the CS GPIO part.

LSM303AGR is a special one in terms of raw value scale among all devices

All values were scaled by 8 instead of 12 for 16g compile-time selected
range. This resulted with values around 6.5 m/s^2. Scaling for runtime
configurable ranges was broken for all except 2g range option due to
totally broken lis2dh_range_to_reg_val().
Fix wrong scaling for 16g compile-time and all runtime selectable ranges
by reworking code that scales raw value. While doing this, change
lis2dh->scale type from 16 to 32 bits. This allows to slightly increase
final result precision by using the fact that raw values have maximum 12
bits precision, allowing us to multiply lis2dh->scale by (1 << 4)
compared to previous implementation.
Fix bug #19872.

Some chips supported by lis2dh driver (such as LIS2DH12 and LIS3DH)
contain CTRL_REG0 (1Eh) register to control internal pull-up on SDO/SA0
line (enabled by default). Add disconnect-sdo-sa0-pull-up boolean
device-tree property to allow disconnecting pull-up during driver
initialization. This allows to save around 180uA at 3.6V in

After switching to new SPI API there is no need to reserve first dummy
byte in buffer and ignore that in application later on. Instead two
buffers can be specified, which is how it is done already in lis2dh
driver. The problem is that dummy byte is still part of the buffer, but
it clearly should no longer be. As an example we write 0x7 (bits to
enable XYZ axes) into CTRL2 instead of CTRL1 register. When reading
measurements on the other hand we have filled buffer starting from 0,
instead of 1 as the driver code has expected.
Fix driver in all places that use burst transfers by removing first
dummy byte from input/output buffer.

Consistently use

instead of

(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).
The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.

Normally a syscall would check the current privilege level and then
decide to go to _impl_<syscall> directly or go through a
_handler_<syscall>.
__ZEPHYR_SUPERVISOR__ is a compiler optimization flag which will
make all the system calls from the driver files directly link
to the _impl_<syscall>. Thereby reducing the overhead of checking the
privileges.
In the previous implementation all the source files would be compiled
by zephyr_source() rule. This means that zephyr_* is a catchall CMake
library for source files that can be built purely with the include
paths, defines, and other compiler flags that all zephyr source
files uses. This states that adding one extra compiler flag for only
one complete directory would fail.
This limitation can be overcome by using zephyr_libray* APIs. This
creates a library for the required directories and it also supports
directory level properties.
Hence we use zephyr_library* to create a new library with
macro _ZEPHYR_SUPERVISOR_ for the optimization.
