Make use of the new DT facilities that introduced two new
bus structures, spi_dt_spec and i2c_dt_spec, as well as the
macros, SPI_DT_SPEC_INST_GET and I2C_DT_SPEC_INST_GET, to
retrieve info from DT.

Add common i2c/spi read/write routines for the benefit of those
ST sensor drivers who make use of the stmemsc HAL i/f.
Add generic stmemsc_cfg_i2c and stmemsc_cfg_spi structures which
contains all relevant information required by i2c/spi low level
routines, such as:
- the pointer to the bus device
- the I2C slave address (if instance is on I2C bus)
- the spi_config structure (if istance is on SPI bus)
This level of abstraction allows the re-use of the i2c/spi read/write
routines among all stmemsc based sensor driver without the need to
reference the specific sensor data and or config structures.
