cmsdk: Allow services to conditionally start before decryption

Browse Source 
* Essentially everything in CMSDK should remain silent when we
   are being prompted to enter a passcode for decrypting the
   device. Unfortunately, simply shutting off CMSDK entirely
   will cause crashes everywhere. We need to be somewhat
   selective about it.
 * Motivation for this was LiveDisplay kicking into night mode before
   decrypted due to location services failing.
