    mmc: sdhci_am654: Write ITAPDLY for DDR52 timing
    
    [ Upstream commit d465234493bb6ad1b9c10a0c9ef9881b8d85081a ]
    
    For DDR52 timing, DLL is enabled but tuning is not carried
    out, therefore the ITAPDLY value in PHY CTRL 4 register is
    not correct. Fix this by writing ITAPDLY after enabling DLL.
