Rename DT_HAS_NODE to DT_HAS_NODE_STATUS_OKAY so the semantics are
clear. As going forward DT_HAS_NODE will report if a NODE exists
regardless of its status.

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
supported by lis2dh.c driver. Apply proper scale factor based on
sensitivity scale provided in LIS2DH and LSM303AGR datasheets.

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.

According to struct sensor_value documentation, val2 should be negative
for negative result. So drop code that tries to make val2 positive.

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
accelerometer power-down mode.

There is little reason to compile lis2dh_reg_field_update() function
conditionally, based on enabled features. If it is not used, then linker
will drop it anyway.

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.

All sensors were using legacy log module registeration method
where LOG_LEVEL was defined before registeration. This method
was error prone as it requires preserving includes order.
Replaced with LOG_MODULE_REGISTER(foo, level).
