[PATCH] tpm: driver for next generation TPM chips

The driver for the next generation of TPM chips version 1.2 including support
for interrupts.  The Trusted Computing Group has written the TPM Interface
Specification (TIS) which defines a common interface for all manufacturer's
1.2 TPM's thus the name tpm_tis.
