[PATCH 4/8] mmc: sdhci: Add SDHCI_SPEC_400, _410, and _420 version defines

[Tanmay Kathpalia]

Add SDHCI_SPEC_400, SDHCI_SPEC_410, and SDHCI_SPEC_420 macros to sdhci.h
to support newer SDHCI specification versions. These defines are required
for compatibility with controllers implementing SDHCI 4.0 and above.
