Description of problem:
1.Support Hygon TKM (Trusted Key Management) running on CSV virtual machine：

All memory data in the CSV virtual machine is encrypted, and the host cannot directly read data from the CSV virtual machine.
Therefore, during the QEMU startup phase, a shared 2MB huge page of memory is reserved for sharing between the host and the CSV virtual machine.
The host kernel converts the CSV's GPA into HPA and directly sends it to the PSP for use.
