tpm_spapr: Support TPM for ppc64 using CRQ based interface

Implement support for TPM on ppc64 by implementing the vTPM CRQ interface
as a frontend. It can use the tpm_emulator driver backend with the external
swtpm.

The Linux vTPM driver for ppc64 works with this emulation.

This TPM emulator also handles the TPM 2 case.
