hwmon: Add driver for I2C chip Nuvoton NCT7363Y
The NCT7363Y is a fan controller which provides up to 16
independent FAN input monitors. It can report each FAN input count
values. The NCT7363Y also provides up to 16 independent PWM
outputs. Each PWM can output specific PWM signal by manual mode to
control the FAN duty outside.
