This patch adds the SDHCI driver and DT binding documentation
for the Nuvoton MA35D1 platform.

This MA35D1 SDHCI driver has been tested on the MA35D1 SOM board with
Linux 6.10

v4:
  - Update to nuvoton,ma35d1-sdhci.yaml
    - Fixing overlooked issues.

v3:
  - Update ma35d1 sdhci driver
    - Fixing "Alignment" and "spaces preferred around".
    - Fixing style for multi-line comments.
    - Fixing double call to sdhci_pltfm_free().

v2:
  - Update to nuvoton,ma35d1-sdhci.yaml
    - Remove some redundant descriptions.
    - Replace 'minitem' with 'maxitem' in the clock settings.
    - Make corrections to nuvoton,sys description.
    - Add sdhci-common.yaml.
    - Remove '|' except where necessary to be preserved.
    - Keeping one example is sufficient.
    - Add regulators in the example.
  - Update ma35d1 sdhci driver
    - Refer to 'include what you use' to modify included header files.
    - Replace the number 8 with sizeof(u8), and similarly for others.
    - Use "dev" instead of "&pdev->dev".
    - Use the min() macro to improve the code.
    - Use dev_err_probe() instead of dev_err().
    - Implement an error reset check mechanism.
    - Add devm_add_action_or_reset() to help with sdhci_pltfm_free().
    - Use devm_reset_control_get_exclusive() instead of devm_reset_control_get().
