At present many TPM calls assume there is only one TPM in the system and look up this TPM themselves. This is inconsistent with driver model, which expects all driver methods to have a device parameter. Update the code to correct this. Also move to u8/32 instead of uint8_t/uint32_t to keep checkpatch happy.
