security/intel/txt: Allow to set TXT BIOS Data Region version

TXT BIOS Data region version is checked by Trusted Boot code. Older
versions of TBoot (e.g. 1.8.2) may refuse to set up the MLE if BDR
version is not known. Provide an option to set the BDR version in
case an older TBoot code is used. This is very useful for platforms
with TPM 1.2.

TEST=Set BDR version to 4 and successfully boot QubesOS 4.0 with
TBoot 1.8.2 on Dell OptiPlex 9010
