Subject: [PATCH 1/4] arm64: dts: qcom: sm8450: move SDHCI pin configuration to DTSI

The SDHCI pin configuration/mux nodes are actually common to all
upstreamed boards, so define them in SoC DTSI to reduce code
duplication.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

In theory drive strength belongs to the board DTS, not SoC DTSI, but I
am following the advice here:
