Revert "Enable ARP offload"

This reverts commit ba800d069ded3b4e3078da0712857fe27c319e7d.
Always disable all LEDs before updating them.

This should make sure the PWMs for red/green/blue always run in sync,
not only when switching between the various light types
(attention/battery/notification).

The kernel now ensures to restart PWM on color change.

Thus, there's no need to do it in user space anymore.
Also, adapt grpfreq and grppwm calculations and comments to actual
in-kernel implementation.
