Subject: [PATCH v2 04/18] ARM: dts: qcom: sdx55: Add support for SDHCI controller

Add devicetree support for SDHCI controller found in Qualcomm SDX55 SoC.
The SDHCI controller used in this SoC is based on the MSM SDHCI v5 IP.
Hence, the support is added by reusing the existing sdhci driver with
"qcom,sdhci-msm-v5" as the fallback.
