This reverts commit cb8ee508ec2d6bc27a8e228021fd1efbd034c4a0.
* Reduce deep-sleep current for VME213 (non-intrusive)
Originally I made an attempt at tidying up the cpuDeepSleep method, but have reverted that. New commit makes only the changes needed to support VME213. Don't really want the headache of breaking sleep for other variants, especially when this PR is just about implementing new boards.
* Update lib_deps; remove board_level extra
