v5 cover add NPCM SDHCI driver support

This patch set adds SDHCI support for the Nuvoton NPCM Baseboard Management Controller (BMC).

Deeply sorry it took that long until sending version three, promise to try to do better on the next versions (if needed) :-),

The NPCM SDHCI driver tested on NPCM750 and NPCM845 EVB.

Changes since version 4:

Changes since version 3:
- Use devm_clk_get_optional_enabled function.
- Add mod_devicetable.h.
- Modify copyright year.

Changes since version 2:
- Add data to handle architecture-specific SDHCI parameters.
- Change config place in make and kconfig files.
- Calling sdhci_pltfm_free to to avoid a memory leak on error.

Changes since version 1:
- Use correct spaces in the dt-bindings.
- Drop unused labels from dt-bindings.
- Order by module name in the make a configuration.
- Remove unnecessary blank lines.
- Using devm_clk_get_optional instead of devm_clk_get.
