[PATCH v6 02/10] qemu: Extend QEMU capabilities with 'spapr-tpm-proxy'

[Daniel Henrique Barboza <danielhb413@xxxxxxxxx>]

Expose the TPM Proxy support for PPC64 guests by creating a new
cap called QEMU_CAPS_DEVICE_SPAPR_TPM_PROXY.

This device is part of the machinery the guest need to orchestrate
with the PPC64 Ultravisor the transition to the Secure VM (SVM)
mode. Inside QEMU, this device will be used with the H_TPM_COMM
hypercall to connect with the TPM Resource Manager, enabling
the guest to open and close TPM sessions with the host TPM.
