drop unnecessary boards, chips and cts tests

The only board which would be built from this branch is Cr50. bds,
fizz and host boards are necessary for proper make infrastructure
operation and tests.

lm4 and npcx are chips used by the bds and fizz boards, so they are
also kept around.

BRANCH=cr50, cr50-mp
BUG=b:145912698
TEST='make buildall -j' succeeds
