[PATCH v2 0/2] Enable emmc and SD on QCS615

[Yuanjie Yang]

Add SDHC1 and SDHC2 support to the QCS615 Ride platform. The SDHC1
and SDHC2 of QCS615 are derived from SM6115. Include the relevant
binding documents accordingly. Additionally, configure SDHC1-related
and SDHC2-related opp, power, and interconnect settings in the device
tree.

Thanks, the binding documents is sdhci-msm.yaml.
I have modified this yaml patch in patch v1, and this yaml patch is
applied, so I remove this yaml patch in patch v2.
