dt-bindings: mmc: sdhci-am654: Update Output tap delay binding

Browse source 
According to latest AM65x Data Manual[1], a different output tap delay
value is recommended for all speed modes. Therefore, replace the
ti,otap-del-sel binding with one ti,otap-del-sel- for each MMC/SD speed
mode.

These bindings must be provided otherwise the driver will disable the
corresponding speed mode (i.e. all nodes must provide at least -legacy)
