feat(qemu): use mock attestation functions for RME
Since QEMU doesn't yet emulate hardware attestation, provide hardcoded key and token to demonstrate attestation for RME. They are copied from the mock values for the FVP platform. Change-Id: I9ce686955345854e9409af5c3aad2a648adea226 Signed-off-by: Jean-Philippe Brucker <jean-philippe@linaro.org>
