arm: msm: smd: fix SMD modem processor sync condition
When booting up we need to wait for the modem processor to partially boot. This is because the modem processor does resource allocation for us. If we don't wait the modem won't honor our requests and we end up crashing or in an unknown state. This change just formalizes the waiting process. Signed-off-by: Daniel Walker <c_dwalke@quicinc.com>
