Move some stuff from apextmo/expressatt to common

- Avoid some code duplication.
- Move camera wrapper from apexq (modify it to fix ISO modes) and
  make it available for other devices (ie: expressatt). Include
  media_profiles.xml for isx012.
- Include some additional scripts.
- Requires some slight changes to device trees.
