Drawcia: Handle more DB FW_CONFIG options
Drawcia: Handle more DB FW_CONFIG options

Ensure all reasonable values for the DB can be handled in the current
board code.  Note this does not cover a 2C DB, as supporting 3 type-c
OCPC ports would require additional board and OCPC development.

BRANCH=None
BUG=b:171742626
TEST=load on drawcia and confirm correct number of PD ports up
