mmc: sdhci-msm: Set dll to good phase while sending cmd13 in tuning

Set the dll to last known good phase before sending status command
while executing tuning. This is to ensure that status command won't
fail due to bad phase. Thus we can avoid sending status command
multiple times and reduce tuning latency.
