mmc: sdhci_am654: Reset command and data lines on failed tuning

Browse Source 
The CMD/DATA reset after tuning should be performed regardless of
whether tuning succeeded or failed, since tuning data may remain in
the buffer in either case. Move the error return after the reset so
that the controller is always cleaned up.
