add command multiplexer to the TPM driver
This code allows to send extension commands over TPM protocol, no
callbacks have been registered yet.
The same buffer is used as input and output data. The header is
stripped off before the callback is called and then re-added after
processing.
This could be used for testing, for proprietary firmware update
protocol, etc.
