mmc: msm_sdhci: Add SDCC version 5.0.0 support

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.
