In the interest of making long-term branch maintenance incur as little
technical debt on us as possible, we should not maintain any files on
the branch we are not actually using.

This has the added effect of making it extremely clear when merging CLs
from the main branch when changes have the possibility to affect us.

The follow-on CL adds a convenience script to actually pull updates from
the main branch and generate a CL for the update.

- * Keyboard power button LED state machine.

- * This sets up TIM_POWER_LED to drive the power button LED so that the duty
- * cycle can range from 0-100%. When the lid is closed or turned off, then the
- * PWM is disabled and the GPIO is reconfigured to minimize leakage voltage.
- *
- * In suspend mode, duty cycle transitions progressively slower from 0%
- * to 100%, and progressively faster from 100% back down to 0%. This
- * results in a breathing effect. It takes about 2sec for a full cycle.
