* Added value to TPM FRU ID

* Default Spectre/Meltdown HW Inits to Kernel mode (#78)

Default Spectre/Meltdown HW Inits used to be "0" Kernel+User
  mitigations.  This commit changes the default to "1" for only
  Kernel mitigations.

I2C addresses were wrong (though not used), this triggers an error to be reported during IPL boot.
