With some support from folks at ARM, I was able to narrow down the issue to Page Tables not correctly configured in EDKII to handle TPM device. After marking the pages in vTPM address range (start:0xFED40000, len:0x5000) as device Pages (ARM_MEMORY_REGION_ATTRIBUTE_DEVICE), I was able to overcome the below reported Exception.
