msm: msm_bus: Use rpmh_write for AWAKE_STATE requests



Use rpmh_write instead of rpmh_write_passthru for AWAKE_STATE
requests to display RSC. The rpmh_write_passthru API did not
allow the rpmh driver to keep track of msm_bus driver's vote and
there was potential for msm_bus wake votes in the tcs to be
overwritten in the event that a new awake/active vote was made
by a different client.
