Ayaneo Air 1S fan control

Hey! The ayaneo air 1s that I have does not allow manual fan speed settings with oxp-sensors. I built nfbc and used ec_probe to poke at the registers that HandheldCompanion has documented and things work, so. It seems there's a bug in the oxp-sensors kernel module.

for example:
```sh
[gamer@chimeraos ~]$ echo 1 | sudo tee /sys/devices/platform/oxp-platform/hwmon/hwmon6/pwm1_enable
1
[gamer@chimeraos ~]$ echo 99 | sudo tee /sys/devices/platform/oxp-platform/hwmon/hwmon6/pwm1
99
tee: /sys/devices/platform/oxp-platform/hwmon/hwmon6/pwm1: Operation not supported
```
the fan spins up but is frozen at something around 2k rpm and no matter what I try to set pwm1 to fails.

vs
```sh
[gamer@chimeraos ~]$ sudo nbfc/pkg/nbfc-linux-git/usr/bin/ec_probe write 0x4a 0x01 #enable manual control
[gamer@chimeraos ~]$ sudo nbfc/pkg/nbfc-linux-git/usr/bin/ec_probe write 0x4b 0x64 #set to 100
```

I've looked at the driver and its quite intimidating. It seems like someone assumed the 1s worked the same as a pile of other devices and I'm not sure where to start. Is anyone familiar with that driver that would be interested in collaborating on a patch? I'm going to try and get fancontrol working for now.
