Add level shifter support for qualcomm SOC's.

`max-sd-hs-frequency` to `max-sd-hs-hz` for clarity.
I just spotted this series, so I'm sorry for jumping in late. To me,
"max-sd-hs-frequency" was actually a better choice, because it goes
together with the already existing "max-frequency" property.
Yes, "max-sd-hs-hz" is obviously more clear, but to me, consistency
is more important. Just my $.02.
- As suggested by Krzysztof Kozlowski remove min/max constraints
and add default: 50000000 in dt-bindings.
- As suggested by Konrad Dybcio moved max-sd-hs-hz property in the
SoC dtsi.
- Retained sdhci-caps-mask in sm8550.dtsi for now and will revisit
its removal for future targets after thorough validation and
testing
from the beginning.
- Changed from v3
- As suggested by Krzysztof Kozlowski moved the property from the
SoC-level DTS to the board-level DTS.
- Revised the commit messages to clearly explain its
board-specific.
- 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.
