From: Nitin Yadav <n-yadav@xxxxxx> UHS Class U1 sd-card are not getting detected due to incorrect OTAP/ITAP delay select values in linux. Update OTAP and ITAP delay select values for various speed modes. For sdhci0, update OTAP delay values for ddr52 & HS200 and add ITAP delay for legacy & mmc-hs. For sdhci1 & sdhci2, update OTAP & ITAP delay select recommended as in RIOT for various speed modes.
