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.
The STMEMSC HAL source code is located here:
