iio: proximity: sx9310: Convert enum->pointer for match data table
Convert enum->pointer for data in match data table, so that
device_get_match_data() can do match against OF/ACPI/I2C tables, once i2c
bus type match support added to it.
Add struct sx931x_info and replace enum->sx931x_info in the match table
and simplify sx9310_check_whoami().
