drivers/i2c: Add a driver for Semtech SX9310
This adds a new driver for the SX9310 proximity detector device. The purpose of this is to enable the device's calibration information to be stored in firmware, and then transferred over to the kernel via ACPI. This device has more than 10 individual configuration parameters, so they would not fit in the generic driver's properties table.
