[PATCH v6 1/5] dt-bindings: mmc: Add dll-presets values for HS400 and HS200 modes

[Ram Prakash Gupta]

From: Sachin Gupta <quic_sachgupt@xxxxxxxxxxx>

Document the 'dll-presets' property for MMC device tree bindings.
The 'dll-presets' property defines the DLL configurations for HS400
and HS200 modes.

QC SoCs can have 0 to 4 SDHCI instances, and each one may need
different tuning.
