spapr: initial implementation for H_TPM_COMM/spapr-tpm-proxy
This implements the H_TPM_COMM hypercall, which is used by an Ultravisor to pass TPM commands directly to the host's TPM device, or a TPM Resource Manager associated with the device. This also introduces a new virtual device, spapr-tpm-proxy, which is used to configure the host TPM path to be used to service requests sent by H_TPM_COMM hcalls, for example: -device spapr-tpm-proxy,id=tpmp0,host-path=/dev/tpmrm0 By default, no spapr-tpm-proxy will be created, and hcalls will return H_FUNCTION. The full specification for this hypercall can be found in docs/specs/ppc-spapr-uv-hcalls.txt Since SVM-related hcalls like H_TPM_COMM use a reserved range of 0xEF00-0xEF80, we introduce a separate hcall table here to handle them.
