Minor - the new chip should be mentioned in drivers/hwmon/Kconfig and in
Documentation/hwmon/lm63.

My main concern is that LM96163 supports a high resolution PWM mode.
Since that mode is much more convenient than the LM63-compatible mode, I
think it is likely to be enabled in designs using LM96163, and it should
be supported by the driver if we add support for LM96163.

Thanks,
Guenter
