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 is possible to explicitly disable drivers that are not needed for particular target.
