drivers/si70xx: Add support for Si705x sensors The Silicon Labs Si705x sensors (Si7050/1/3/4/5) are very similar to the Si7021 sensors featuring only a temperature sensor and no humidity sensor. The only difference between the Si705x is the temperature accuracy of the reading, ranging from +/- 0.1 C in the Si7051 to +/- 1 C in the Si7050. This patch adds support for this family of sensors extending the functionality of the existing si70xx driver. Following the style of other modules, this implements a pseudomodule per supported chip, adding si7050, si7051, si7053, si7054 and si7055 pseudomodules. As a minor change this patch also implements the missing si70xx_get_serial, si70xx_get_id and si70xx_get_revision functions that were declared in the si70xx.h header but implemented as private functions. The si70xx_get_id() may be relevant for the application to know at run time exactly which version of the hardware is installed. The updated test running with a Si7051 shows the following output, which seems consistent with the room temperature conditions during the test. ``` make SI70XX_VARIANT=si7051 -C tests/driver_si70xx/ all flash ``` ``` SI70XX temperature and humidity sensor test application Initializing sensor... [OK] Found SI7051 sensor, revision 32 temperature: 24.71 C temperature: 24.69 C ```
