For SDCC version 5.0.0, MCI registers are removed from SDCC interface and some registers are moved to HC. So add support to use the new compatible string "qcom,sdhci-msm-v5". Based on this new msm variant, pick the relevant variant data and use it to detect MCI presence thereby configuring register read/write to msm specific registers.
