mb/google/dedede: Use a separate ec.h for dibbi variants

Dibbi variants are chromeboxes, so they need different settings in ec.h.
Add a new dibbi baseboard ec.h and use it for dibbi variants. For now
it's identical to the dedede baseboard ec.h. It will be updated in the
following CL.

BUG=b:294963793
TEST=With the following CL, boot dibbi and check the APCI tables no
longer contain lid and PS/2 keyboard devices.
