Re: [PATCH 1/1] hwmon: (oxp-sensors) Add support for multiple new devices.

Add support for the OrangePi NEO-01. It uses different registers for PWM
manual mode, set PWM, and read fan speed than previous devices. Valid PWM
input and duty cycle is 1-244, we scale this from 1-255 to maintain
compatibility with the existing interface.

Add OneXPlayer 2 series and OneXFly models. The 2 series uses a new
register for turbo button takeover. While at it, adjust formatting of some
constants and reorders all cases alphabetically for consistency. Rename
OXP_OLD constants to OXP_MINI for disambiguation.

Adds support for AYANEO models 2S, AIR 1S, Flip DS, Flip KB, GEEK 1S, and
KUN.
