Subject: [PATCH] mmc: dw_mmc: hide clock message when card is resuming

Commit e9748e0364fe ("mmc: dw_mmc: force setup bus if active slots exist")
made a change resulted in clock message appears every time the card is
resuming (every 5 second in average). Add condition that previously used to
print the message.
