Subject: [PATCH V3] arm64: dts: qcom: sc7180: Add nodes for eMMC and SD card
From: Veerabhadrarao Badiganti <vbadigan@...eaurora.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.

Changes since V2:
- Added cmdq register space and support-cqe flag.
- Incorporated review comments by Matthias Kaehlcke.
Changes since V1:
- Updated the regulator min, max voltages as per
eMMC/SD-card voltage requirements
- Enabled IOMMU for eMMC and SD-card.
- Added pull and drive strength to SD-card cd-gpio.
- Incorporated review comments by Matthias Kaehlcke.
