tpm: Implement tpm20_menu
In the TPM 2 menu we currently only allow to run the TPM2_Clear operation.
For this we follow the TCG Physical Presence Interface Specification
to be found here:
http://www.trustedcomputinggroup.org/resources/tcg_physical_presence_interface_specification
Table 3 shows the 'Clear' operation and the sequence of commands to send.
