Subject: [PATCH V2 1/2] dt-bindings: mmc: sdhci-msm: Add new compatible string for sdcdc10 DLL

On the SDHC-MSM controllers which makes use of sdcdc10 variant DLLs,
the DLL configuration needs to be restored whenever controller clocks
are gated. This new compatible string denotes the sdhc-msm controller
variant which uses sdcdc10 DLL.
