Subject: [PATCH v2 1/2] dt-bindings: mmc: sdhci-msm: document resets

Commit "mmc: sdhci-msm: Reset GCC_SDCC_BCR register for SDHC" added
support for utilizing a hardware reset and parsing it from DT, however
the bindings were not updated along with it.

So, document the usage of "resets" property with the limit of only one
item.
