mmc: sdhci_am654: Add Support for 4 bit IP on J721E

Browse source

Add support for 4 bit instances on TI's J721E devices. Because these
instances have no DLL, introduce a DLL_PRESENT flag and make sure DLL
related registers are only accessed when it is present. Also add a
separate set_clock callback for this compatible.
