drivers: Add I2C TPM driver to coreboot

Hardware / Coreboot - Stefan Reinauer [chromium.org] - 10 August 2014 15:25 UTC

On ARM platforms the TPM is not attached through LPC but through I2C. This patch adds an I2C TPM driver that supports the following chips:
- Infineon SLB9635
- Infineon SLB9645 In order to select the correct TPM implementation cleanly, CONFIG_TPM is moved to src/Kconfig and does the correct choice.
