Add SD Card support for sm8750 SoC, including MTP and QRD boards.

- Changed from v3
    - As suggested by Krzysztof Kozlowski refactor the code to follow
      DTS coding style and use hex everywhere in reg.

- Changed from v2
    - As suggested by Abel Vesa move the GPIO configuration for SD card
      detection (specifically the pin settings for gpio55) from the
      SoC-level device tree (sm8750.dtsi) to the board-specific device
      tree files.

- Changed from v1
    - As suggested by Konrad Dybcio the patch into separate commits per
      board and did formatting improvements (e.g. aligning < symbols,
      placing each item on a new line).
    - Addressed Konrad Dybcio comment to use SVS_L1 for opp-202000000.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/v6.18-rc1-53-gc2703c90161b (exact match)
 Base: tags/v6.18-rc1-53-gc2703c90161b (use --merge-base to override)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
