Hi,

This patch adds support for the PWM frequencies from 22.5 to 30 kHz
available on the LM96000.

It looks like this chip has been supported for a long time, but wasn't
mentioned in the docs (which I have updated).

Also, it has been using the generic 'lm85' prefix, which I have not
changed to avoid breaking userspace or device tree files. AFAICT,
lm85_detect() will only return 'lm85' for LM96000 chips, so it doesn't
look like you can get a bare 'lm85' prefix with any other chips.

I stumbled on to a 10 year old thread discussing a patch which looks
like an early attempt to add support for this chip, which may be of
interest:

Thanks for reviewing,

Jeremy

Changes since v1:
 - replace freq_map_mask with freq_map_size
