servo: add support for new lucid with swd flex

The new rev of lucid uses the swd servoflex instead of the cosmos flex.
This change replaces the old lucid overlay with one that uses the swd
flex and adds an overlay for the lucid boards that use cosmos.

BUG=none
BRANCH=none
TEST=use 'servod -b lucidcosmos' works with the old boards, and 'servod
-b lucid' works with the current boards.
