Speed modes supported has been already updated in PATCH eb8f6194e807. 'ti,strobe-sel' property is only required by HS400 speed mode and thus needs to be removed from kernel dtsi for J721e soc. 'ti,strobe-sel' is read in sdhci_am654.c line 733 and gets stored in sdhci_am654->strb_sel. This sdhci_am654->strb_sel is used at only one place in sdhci_am654.c line 291 which will only get used if HS400 is enabled. Thus, drop 'ti,strobe-sel' property from kernel dtsi for J721e soc.
