This patch makes I2C and SPI interface drivers for STMicroelectronics
sensor chips individually selectable via Kconfig.
The default is kept unchanged - I2C and SPI interface drivers are still
selected by default if the corresponding bus support is available.
However, the patch makes it possible to explicitly disable drivers
that are not needed for a particular target.

The same question as per v2.
+ default I2C && IIO_ST_ACCEL_3AXIS
What will be the results when I2C=y and the second ones =m?
$ grep CONFIG_I2C= .config
CONFIG_I2C=y
$ grep IIO_ST_ACCEL .config
CONFIG_IIO_ST_ACCEL_3AXIS=m
CONFIG_IIO_ST_ACCEL_I2C_3AXIS=m
# CONFIG_IIO_ST_ACCEL_SPI_3AXIS is not set
$ vim .config
<remove CONFIG_IIO_ST_ACCEL_I2C_3AXIS line>
$ grep IIO_ST_ACCEL .config
CONFIG_IIO_ST_ACCEL_3AXIS=m
# CONFIG_IIO_ST_ACCEL_SPI_3AXIS is not set
$ make menuconfig
<immediately exit>
$ grep IIO_ST_ACCEL .config
CONFIG_IIO_ST_ACCEL_3AXIS=m
CONFIG_IIO_ST_ACCEL_I2C_3AXIS=m

CONFIG_IIO_ST_ACCEL_I2C_3AXIS was set to =m by default. I believe this is correct behavior.
