cr50: limit ability to disable TPM to certain boards
The TPM disable function requires support from the AP firmware side,
only certain Chrome OS devices provide this support.
This patch adds a board property for this capability and enables it
for the Wilco family of boards.
BRANCH=cr50, cr50-mp
BUG=b:133189891
TEST=verified that Wilco still could be taken through diagnostics mode
back to normal while maintaining the user account.
