[PATCH V2 0/4] Add SD Card support for sm8750 SoC and boards

[Sarthak Garg]

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

- 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.
