[PATCH] conf: Set SPAPR TPM default to 2.0 and prevent 1.2 choice

From: Stefan Berger <stefanb(a)linux.ibm.com&gt; The firmware (SLOF) on QEMU for ppc64 does not support TPM 1.2, so prevent the choice of TPM 1.2 when the SPAPR device model is chosen and use a default of '2.0' (TPM 2) for the emulator.
