I must apologize, the 0 RPM reading was my mistake. The RPM reading actually
works perfectly fine! There is just a slight normal delay in the EC updating
the value after the fans spin up. I re-tested it, and the RPM values are being
reported correctly.

Also, writing 1 to `pwm1_enable` works flawlessly, and adjusting `pwm1` from 0
to 255 scales the fan speed smoothly and exactly as expected.

Thank you so much for your fast and incredibly effective help!
