hwmon: (lm85) add support for LM96000 high frequencies 

The LM96000 expands the freqency field from 3 to 4 bits, to
add more frequencies in the 22.5 to 30 kHz ranges.

The LM96000 supports additional high frequency PWM modes (22.5 kHz, 24 kHz,
25.7 kHz, 27.7 kHz and 30 kHz), which can be configured on a per-PWM basis.
