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.
