Add a new uclass for TPMs which uses almost the same TIS (TPM Interface Specification) as is currently implemented. Since init() is handled by the normal driver model probe() method, we don't need to implement that. Also rename the transfer method to xfer() which is a less clumbsy name. Once all drivers and users are converted to driver model we can remove the old code.
