HTS221 is a humidity and temperature sensor (thus HTS) that can be wired
on i2c or SPI bus. On SPI bus however, it uses the 3-wire mode, aka:
half-duplex.
Now that SPI API exposes half duplex operation, let's enable the SPI bus
on that sensor.
Let's move to a better DTS integrated driver as well, and also use
stmemsc interface.

Both DRDY and motion interrupts behaves like level signals since they
remain asserted until they're cleared. Configuring them as edge
interrupts is dangerous because if we ever miss an interrupt, it may
never get cleared and thus will never trigger again.
Treating them as edge signals seems to have no advantages, other than
being marginally simpler to implement.
The patch has gotten many hours of run-time on real hardware using a
nRF52-based board and a LIS3DH with both interrupts connected and
heavily utilized.

In order to convert from degrees to radiants the SENSOR_DEG2RAD_DOUBLE
macro must divide the argument by 180 degrees and multiply by PI
radiants, and not the other way around. Please note that same macro
is already defined in the correct way in other sensor drivers as well.

Fix the usage of sensor shell module that calls sensor_sample_fetch
function with SENSOR_CHAN_ALL id which is not supported and

- Per datasheet (Rev 1.0, Page 29): When enabling adv_power_save, there
needs to be a 1ms inter-write registers delay. With this addition, the
driver will work at SCLK frequencies faster than 100kHz.
- Added helper function reg_write_with_delay() to factor these writes.

On LSM6DSO sensor the INT1 pin is used for both generating the drdy
interrupt and for switching to I3C hotjoin mode just after reset if
it is at logical '1' level. It might happen that after a board
reset the logical level '1' is preserved (maybe a level shifter)
forcing the LSM6DSO to enter erroneously in I3C mode, breaking any
attempt to communicate with it. (Fix#38902)
