[PATCH v2 1/6] arm64: dts: ti: k3-am65-main: Update sdhci properties

Tue Apr 16 15:16:43 PDT 2024
Update otap-del-sel properties as per datasheet [0].
Add missing clkbuf-sel and itap-del-sel values also as per
datasheet [0].
Move clkbuf-sel and ti,trm-icp above the otap-del-sel properties
so the sdhci nodes could be more uniform across platforms.
