Add the dt-bindings and the driver for tmp117 sensor.

Changes since v3:
1. Remove bug related to caching the calibbias.
2. Expand NV to Non-Volatile.
3. Include limits.h and use its macros in clamp().
Changes since v2:
1. Made Calibbias read and write in same units.
2. Add missing includes.
3. Clamp the values before writing to calibbias.
4. Add i2c description to dt-binding example.
5. Remove explicit casting at different places.
Changes since v1:
1. Remove unused headers
2. Add error checking in i2c read/write.
3. Correct DT bindings.
4. Correct implementation to return tmp in milli celcius.
5. Remove unused mutex lock.
6. Modify MAINTAINERS.
Changes since v0:
1. Correct Yaml syntax.
2. Change IIO_CHAN_INFO_OFFSET to IIO_CHAN_INFO_CALIBBIAS.
3. Implement IIO_CHAN_INFO_SCALE.
4. Use devm_iio_device_register().
5. Remove unused headers like delay.h
