Revert "kodama: drop kodama board"

This reverts commit 3f50a1e35e093d3989dc27f340b4ce5fb7fca5ee.

Reason for revert: The kukui-arc-r-postsubmit builder started failing after this change landed:
https://buganizer.corp.google.com/issues/204520684
https://ci.chromium.org/p/chromeos/builders/postsubmit/kukui-arc-r-postsubmit

The error is that the kodama board wasn't found.
chromeos-ec-0.0.2-r11157: Makefile:25: *** unable to locate BOARD kodama.  Stop.
chromeos-ec-0.0.2-r11157:  * ERROR: chromeos-base/chromeos-ec-0.0.2-r11157::chromiumos failed (compile phase):


Original change's description:
> kodama: drop kodama board
>
> Kodama is the tightest space board in kukui family, and we
> have to constanly disable configs to free up space.
> Since we don't really need the board in main branch as the
> firmware branch has been created for a long time, just drop
> this board on main branch.
>
> BUG=none
> TEST=makd buildall
> BRANCH=main
