arm64: dts: ti: k3-am62-main: Update OTAP and ITAP delay select
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.
revert "arm64: dts: ti: Disable UHS speed modes on MMCSD1 instance"
This reverts commit bbe3a26e0adcad44ef9776ec7d3a46f73b441df2 to
renable UHS mode support.
