tpm: Add field upgrade mode support for Infineon TPM2 modules
TPM2_GetCapability with a capability that has the property type value
of TPM_PT_TOTAL_COMMANDS returns a zero length list, when an Infineon
TPM2 is in field upgrade mode.
Since an Infineon TPM2.0 in field upgrade mode returns RC_SUCCESS on
TPM2_Startup, the field upgrade mode has to be detected by
TPM2_GetCapability.
