This patch ensures that entire system memory calculation is done
based on host bridge registers.
BRANCH=none
BUG=b:63974384
TEST=Build and boot cannonlake RVP successfully with below configurations
1. Booting to OS with no UPD change
2. Enable ProbelessTrace UPD and boot to OS.
3. Enable PRMRR with size 1MB and boot to OS.
4. Enable PRMRR with size 32MB and boot to OS.
5. Enable PRMRR with size 2MB and unable to boot to OS due to
