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

- Changed from v4
    - As suggested by Konrad Dybcio sort nodes with a unit address
      (numbers after @) by that register address.

- 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.
