Add level shifter support for qualcomm SOC's.

- Changed from v2
    - As suggested by Konrad Dybcio and Ulf Hansson redesigned logic
      to introduce a new DT property max-sd-hs-frequency and override
      the hs_max_dtr accordingly in sd.c file.

- Changed from v1
    - As suggested by Krzysztof Kozlowski redesigned logic to use
    compatible property for adding this level shifter support.
    - Addressed Adrian Hunter comments on V1 with resepect to
      checkpatch.
    - Cleared the bits first and then set bits in
      sdhci_msm_execute_tuning as suggested by Adrian Hunter.
    - Upated the if condition logic in msm_set_clock_rate_for_bus_mode
      as suggested by Adrian Hunter.
