Rather than looking up a dummy item from SMEM, use the new qcom_smem_is_available() function to make the code more clear (and reduce the overhead slightly). Add the same check to qcom_smd_register_edge() as well to ensure that it only succeeds if SMEM is already available - if a driver calls the function and SMEM is not available yet then the initial state will be read incorrectly and the RPMSG devices might never become available.
