ec/google/wilco: Support board_id with EC provided ID
The EC can return a board ID value similar to the Chrome EC.
In order to use this for the board version returned by SMBIOS
this commit implements the board_id() function for mainboards
that use this EC.
BUG=b:123261132
TEST=Check /sys/class/dmi/id/board_version to see that it
is reflecting the value that the EC provides.
