arm64: dts: qcom: sm8450: disable SDHCI SDR104/SDR50 on all boards
SDHCI on SM8450 HDK also has problems with SDR104/SDR50:
mmc0: card never left busy state
mmc0: error -110 whilst initialising SD card
so I think it is safe to assume this issue affects all SM8450 boards.
Move the quirk disallowing these modes to the SoC DTSI, to spare people
working on other boards the misery of debugging this issue.
