hv: vapci: add tpm2 support for pre-launched vm

Browse Source 
On WHL platform, we need to pass through TPM to Secure pre-launched VM. In order
to do this, we need to add TPM2 ACPI Table and add TPM DSDT ACPI table to include
the _CRS.

Now we only support the TPM 2.0 device (TPM 1.2 device is not support). Besides,
the TPM must use Start Method 7 (Uses the Command Response Buffer Interface)
to notify the TPM 2.0 device that a command is available for processing.
