ec: docs: Fully document how protection works

Project Member Reported by sha...@chromium.org, Feb 6 2017 
We have two slightly different schemes (pstate vs external SPI protection), and the r*_at_{boot/now} flags are confusing some people, so it would be nice to document this stuff completely on chromium.org to avoid re-explaining it frequently.

We'll also need to update it to support CCD V1 control of WP.
