Subject: [PATCH 10/39] arm64: dts: qcom: sdm630: Add interconnect and opp table to sdhc_1

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@...ainline.org>

The SDHC port 1 has interconnects and can make use of DVFS:
define the interconnections and the OPP table in order to
optimize performance and power consumption.
