t132: Add support for tpm i2c
Iniitialize I2C bus required for TPM operation. Problem observed was that if
frequency is raised above 20KHz, TPM starts responding with NAKs either for
address or for data. Need to look into that.
BUG=None
BRANCH=None
TEST=Compiles successfully and TPM success messages seen while booting.
