- Add DM based generic watchdog start and reset implementation
  and remove all ad-hoc implementations (Stefan)
- Move mv_sdhci to DM (Pierre)
- Misc turris_omnia updates (Pierre)
- Change openrd targets to correctly build again (size changes
  and fixes to the dts targets) and bring it back into Travis
  builds (Stefan)
- Add Kirkwood db-88f6281-bp board (Chris)
