Disable boards which does not fulfil new ticker standards.

This has been done already here:
7f88de9

Unfortunately targets.json file is changed quite often and it is hard to maintain conflicts while rebasing feature branch on master.
This will have to be cleaned up later for integration with master.

Note:
lp ticker is required to have flash support on NRF52_DK. Disable flash support for this board.
