security/intel/cbnt: Make CBNT compatible with CMOS option table
Make sure the bytes in RTC cmos used by CBNT don't collide with the
option table. This depends on what is set up in the BPM, Boot Policy
Manifest. When the BPM is provided as a binary the Kconfig needs to be
adapted accordingly. A later patch will use this when generating the
BPM.
