drivers/i2c/tpm: Add support for Atmel TPM (AT97SC3204)
The I2C interface for the Atmel AT97SC3204 TPM varies greatly from the
existing I2C TPM support. The Atmel part just passes the commands and
responses from the TIS layer across the I2C interface.
TEST=Build and run on Galileo Gen2 with Crypto Shield and vboot enabled
