[PATCH V1 2/2] arm64: dts: qcom: sc7180: Add nodes for eMMC and SD card

[Veerabhadrarao Badiganti <vbadigan@codeaurora.org>]

Add sdhc instances for supporting eMMC and SD-card on sc7180.
The regulators should be in HPM state for proper functionality of
eMMC and SD-card. Updating corresponding regulators accordingly.
