From: Amir Mizinski <amirmizi6@gmail.com>
Added a YAML schema to support tpm tis i2c realted dt-bindings for the I2c PTP based physical layer.
This patch adds the documentation for corresponding device tree bindings of I2C based Physical TPM. Refer to the 'I2C Interface Definition' section in 'TCG PC Client PlatformTPMProfile(PTP) Specification' publication for specification.
