Secure Boot: Support Phyp debug flag in HDAT
PHYP needs a way to know if SBE security backdoor is enabled for debug purposes. This change creates a flag in TPM instance data structure to indicate whether the backdoor is enabled. This flag is passed by SBE to the hb bootloader; also added the flag to indicate whether PCR is poisoned (default of 0). The population of this flag will be implemented on Fleetwood.
