fwk: only build dogwood

We don't need to build other boards on this branch.
Remove them, it saves build time and mental load on keeping them happy.

fwk-main is for integrating with other boards and making sure
they're all happy, and hopefully cherry-picking is paired with actually
trying on those physical boards (eg: right now it's wishful thinking
that marigold.bin from the fwk-dogwood branch is even workable/boots).

TEST=See Github CI, only see dogwood in the list
TEST=Introduce an error to another branch, CI still oblivious
BUG=Discovered during PR#1571
BRANCH=fwk-dogwood-27111
